Answer:
A query in a database is a request for information stored within a database management system (DBMS), which is the software program that maintains data.
SQL(Structured Query Language ( is a standard language for storing, manipulating, and retrieving data in database.
Five types of SQL queries are:
1) Data Definition Language (DDL).
used to define and modify the structure of a database.
2) Data Manipulation Language (DML).
used to manipulate (change) the data in the database.
3) Data Control Language(DCL).
used for access control and permission management for users in the database.
4) Transaction Control Language(TCL).
used for maintaining consistency of the database and for the management of transactions made by the DML commands.
5) Data Query Language (DQL).
used for performing queries on the data within schema objects.

Daisy loves playing games with words. Recently, she has been playing the following Deletive Editing word game with Daniel.
Daisy picks a word, for example, "DETERMINED". On each game turn, Daniel calls out a letter, for example, 'E', and Daisy removes the first occurrence of this letter from the word, getting "DTERMINED". On the next turn, Daniel calls out a letter again, for example, 'D', and Daisy removes its first occurrence, getting "TERMINED". They continue with 'I', getting "TERMNED", with 'N', getting "TERMED", and with 'D', getting "TERME". Now, if Daniel calls out the letter 'E', Daisy gets "TRME", but there is no way she can get the word "TERM" if they start playing with the word "DETERMINED".
Daisy is curious if she can get the final word of her choice, starting from the given initial word, by playing this game for zero or more turns. Your task it help her to figure this out.
% deletiveEditing(Initial,End).
Each word consists of at least one and at most 30 uppercase English letters; Initial is the Daisy's initial word for the game; End is the final word that Daisy would like to get at the end of the game.

give an example of an algorithm in c++ that can be used to avoid car collision using four infra red sensors
Answer:
Since entering the 21st century, the number of vehicles has increased exponentially, and the number of vehicles and drivers has further increased [1]. How to reduce the number of traffic accident deaths and economic losses has become an important issue in the context of such a large number of vehicles [2].
In recent years, some research studies have been made on the collision warning algorithm. The existing collision warning algorithms are mainly divided into two categories, namely, the Safety Time Algorithm and the Safety Distance Algorithm [3]. The safety time logic algorithm compares the collision time between the two workshops with the safety time threshold to determine the safety status. The safety time algorithm mainly uses Time to Collision (TTC) as the research object [4]. The safety distance model refers to the minimum distance between the vehicle and the obstacle, which is also the distance the vehicle needs to maintain to avoid the collision with the obstacle under the current conditions of the vehicle [5].

What will be printed to the screen when the following program is run?
Answer:
20
Explanation:
max(my_list) is 5 (finds the maximum value)
sum(my_list) is 1 + 2 + 3 + 4 + 5 = 15 (finds the sum of values)
=> max(my_list) + sum(my_list) = 5 + 15 = 20
Answer:
It will print 20, because you are adding all the values of your list together using the max function, and then adding the actual integers in your list together with the previous number.

Answer:
Explanation:

I don't think I would choose Rubik's Cube, although I think many people would. It does have a depth of something that moves in all three dimensions, but lot's of things do that. It was more of a craze than something of every lasting value.
Pong is a game. Game software has advanced so dramatically that I don't think you know anyone who has played Pong. You could argue it was a beginning -- but there are others that shared that distinction like Pacman.
Do you know anyone who ever owned an Altair 8000? I don't. by then the Apple 2 was well on its way. And so was Apple which is a huge corporation.
