#include <map>
using namespace std;
int main()
{
map<int, int> numbers;
cout << "Enter numbers, 0 to finish" << endl;
int number;
while (true) {

numbers[number]++;
}
for (pair<int, int> element : numbers) {
std::cout << element.first << ": occurs " << element.second << " times" << std::endl;

Explanation:
One trick used here is not to keep track of the numbers themselves (since that is not a requirement), but start counting their occurrances right away. An STL map< > is a more suitable construct than a vector< >.
g Create a Java program that takes input of a list of integers from the user, stores them into an array and then finally uses the array contents to output the list of integers in reverse. The user's input begins with the number of integers to be stored in the array. For coding simplicity, follow each output integer by a space, including the last one. Assume that the list will always contain fewer than 20 integers.Create a Java program Ex: If the input is: 8 5 2 3 4 10 6 8 9
Answers
Answer:
import java.util.Scanner;
public class Main{
public static void main(String[] args) {
int arraylent;
Scanner input = new Scanner(System.in);
System.out.print("Array Length: ");
arraylent= input.nextInt();
int[] myarray = new int[arraylent];
for(int i = 0; i<arraylent;i++)
myarray[i] = input.nextInt();
for(int i = arraylent-1; i>=0;i--)
System.out.println(myarray[i]);
}
}
Explanation:
This declares the length of the array
int arraylent;
This next two lines prompt and get the array length i.e. number of input
System.out.print("Array Length: ");
arraylent= input.nextInt();
This declares the array as type integer. And the length of the array is gotten from the user input
int[] myarray = new int[arraylent];
This gets the items of the array
for(int i = 0; i<arraylent;i++)
myarray[i] = input.nextInt();
This reverse and prints the array
for(int i = arraylent-1; i>=0;i--)
System.out.println(myarray[i]);
Write a program with a method called passwordCheck to return if the string is a valid password. The method should have the signature shown in the starter code.
The password must be at least 8 characters long and may only consist of letters and digits. To pass the autograder, you will need to print the boolean return value from the passwordCheck method.
Hint: Consider creating a String that contains all the letters in the alphabet and a String that contains all digits. If the password has a character that isn’t in one of those Strings, then it’s an illegitimate password!
Coding portion:
public class Password
{
public static void main(String[] args)
{
// Prompt the user to enter their password and pass their string
// to the passwordCheck method to determine if it is valid.
}
public static boolean passwordCheck(String password)
{
// Create this method so that it checks to see that the password
// is at least 8 characters long and only contains letters
// and numbers.
}

Explanation:
The Java class "Password" is used by the program to make an instance of the password object and check its validity with the passwordChecker method defined within the Password class. The passwordChecker method only matches alphanumeric passwords, that is, passwords with alphabets and numbers. If a non-alphanumeric character is encountered, the boolean value false is returned.

Write a program that reads a stream of integers from a file and prints to the screen the range of integers in the file (i.e. [lowest, highest]). You should first prompt the user to provide the file name. You should then read all the integers from the file, keeping track of the lowest and highest values seen in the entire file, and only print out the range of values after the entire file has been read.
Answers
Answer:
This question is answered using C++ programming language
#include <fstream>
#include<iostream>
using namespace std;
int main() {
string fname;
cout<<"Enter Filename: ";
cin>>fname;
int lowest = 0;
int highest = 0;
ifstream ifs(fname);
int x;
while (ifs >> x){
if(x < lowest){
lowest= x;
}
if(x > highest) {
highest = x;
}
}
ifs.close();
for(int i = lowest; i<=highest;i++)
{
cout<<i<<" ";
}
}
Explanation:
This line declares fname as string
string fname;
This prompts user for filename
cout<<"Enter Filename: ";
This gets filename
cin>>fname;
This declares and initializes lowest to 0
int lowest = 0;
This declares and initializes highest to 0
int highest = 0;
This defines the file using ifstream
ifstream ifs(fname+".txt");
This declares x as integer. x is used to read integers in the file
int x;
The following iteration will be repeated until there is no other integer to be read from the file
while (ifs >> x){
This checks for lowest
if(x < lowest){
lowest= x;
}
This checks for highest
if(x > highest) {
highest = x;
}
}
This closes the file. i.e. the file has been read
ifs.close();
The following iteration prints the range of values from lowest to highest
for(int i = lowest; i<=highest;i++) {
cout<<i<<" ";
}
Please note that the filename must be entered with its extension

Explanation:
This is a multiple choice question and this is the answer because:
1. OpenMp is inclusive of an APL/compiler directives:
2. any code which follows #pragma omp parallel is a parallel region and it is performed by large number of threads that are same as the number of processing cores that are in the system.
3. The critical-section compiler directive acts more like a binary semaphore or mutex lock,it makes sure that only one thread is active in the critical section at the same time.
PLS HELP ASAP- Select the correct text in the passage.
Which concept explained in the paragraph below means that data always remains consistent?
Specific programs have some tasks that a computer must perform in parallel with others. These tasks (such as the performance of the same set of operations on different data sets) often work in parallel clusters. In such cases, a separate thread of execution handles each separate task. You can think of a thread as a sequence of instructions that computers can manage independently.
It is possible for different threads to access the same data elements and change their values, and this can lead to an inconsistent state of information. For instance, if multiple programs access a shared variable x and change its value, the variable will not contain the correct value at the end of the programs. We can prevent such inconsistencies by using locks. A thread puts a lock on shared data, and releases this lock only after completing its operations.

In python, Write a function (name: identi Substring) that, given a string S, returns an integer that represents the numbers of ways in which we can select a non-empty substring of S where all of the characters of the substring are identical. Two substrings with the same letters but different in locations are still considered different. For example, the string "zzzyz" contains 8 such substrings. Four instances of "z", two of "zz", one of "zzz" and one instance of "y". String "k" contains only one such substring:"k". The length of S will be between 1 and 100, inclusive. Each character in S will be a lowercase letter (a-z).
Answers
Answer:
def identiSubstring(S):
n = len(S)
inst = ""
count= 0
for Len in range(1,n+1):
for i in range(n-Len+1):
for k in range(i,i + Len):
inst =inst+S[k]
if(len(set(inst)) == 1):
count = count + 1
inst = ""
return count
S = input("Enter a string: ")
if(len(S)>=1 and len(S)<=100):
print("There are "+str(identiSubstring(S.lower()))+" possible occurrences")
else:
print("Length is invalid")
Explanation:
This line defines the required function
def identiSubstring(S):
This calculates the length of string S
n = len(S)
This initializes an instance of the required string to an empty string
inst = ""
This initializes count to 0
count= 0
This following iterations iterate through the length of the string
for Len in range(1,n+1):
for i in range(n-Len+1):
for k in range(i,i + Len):
This gets an instance of string S
inst =inst+S[k]
This checks if the characters of the instance are identical
if(len(set(inst)) == 1):
If yes, the counter is incremented by 1
count = count + 1
This instance is reset back to an empty string
inst = ""
This returns the number of instances of the substring
return count
The main begins here
This prompt user for a string
S = input("Enter a string: ")
This checks for valid length
if(len(S)>=1 and len(S)<=100):
If length is between 1 and 100 (inclusive), this calls the identiSubstring function
print("There are "+str(identiSubstring(S.lower()))+" possible occurrences")
If otherwise
else:
This prints invalid length
print("Length is invalid")

The answer is "F1"
Explanation:
Please find the complete question in the attachment file.
The F1 key is also known as the function key, which can be used to configure on a device or console key to cause such actions, a form of a soft button, to also be performed by a web browser control parser or software application. The main purpose of the F! key is to open the Help screen for all programs.
In a text messaging system, data is sent from one device to another. Devices are recognized by a unique device ID. The format of the message is sent as a string with information about the number of characters in the device ID, the device ID itself, the number of characters in the text message and the text message that is being sent with each part being separated by a space. The system uses this information to send the message to the correct device and the receiving device displays only the text message. The number of words in the text message is also useful. A word is defined by strings separated by spaces.
Here is a sample VALID message:
04 1234 05 hello
The first two digits in the string represent the length of the device ID to follow.
The device ID is the number of characters following the length. Note that the device ID may not be limited to number values.
Following the device ID is the length of the text message and then the text message itself. The text message may be any combination of characters (such as letters, numbers or symbols) and may include spaces.
This message contains one word.
Here is a sample INVALID message:
06 a2b10 09 I’m ready
The first two values 06 indicate the device ID length. The device ID is a2b10 which has a length of 5. This does not match the specified length 06. Thus, this is NOT a valid message.
This message contains two words.
The Message class represents messages in this system. A Message must have a device ID, the length of the ID, the length of the message and the text message being sent in order to be a valid message sent through the system. The Message class must determine if a message is valid in order to send a message. A valid message is one where the device ID length matches the given length in the message string and the text message length matches the length of the supplied text message. The text message consists of one or more words where the length of the text message string is at least one character.
Consider the code below:
Message msg1 = new Message("08 abc123xy 16 Computer Science"); //creates a new message object
boolean msg1Valid = msg1.isValid(); // returns true for a valid message
String text = "11 radio11a287 14";
Message msg2 = new Message(text);
boolean msg2Valid = msg2.isValid(); // returns false for an invalid message
Message msg3 = new Message("04 92a1 16 Computer Science");
Message msg4 = new Message("03 x8r 21 Today is a great day!");
int numWords = msg4.wordCount(); //returns 5, the number of words in the
//text message
Complete the Message class by writing the isValid() and wordcount() methods.
public class Message{
private int idLength;
private String deviceID;
private int msgLength;
private String textMsg;
public Message(String msg){
//implementation not shown
}
public boolean isValid(){
//to be written
}
public int wordCount(){
//to be written
}
Answers
Answer:
public int wordCount() {
String[] arr = textMsg.split(" ", 0);
return arr.length();
}
public boolean isValid() {
if (idLength == deviceID.length()) {
if (msgLength == textMsg.length()) {
return true;
} else {
return false;
}
return false;
}
Explanation:
The Java source code defines two methods in a class named Message namely; isValid() and wordCount(). The isValid() method evaluates the validity of a message sent to return a boolean value while the wordCount() counts and returns the number of words in the message.
