By deducting the gain ratio of the splitting from the index of both the parent node, it is possible to determine the increase in the gain coefficient when dividing on a and b.
What is algorithm?
An algorithm is a set of instructions or steps that are designed to solve a problem or accomplish a task. It is an effective way of performing a task that can be repeated, with the same results each time. Algorithms are commonly used in computer programming and can range from simple to complex. They can be used to solve simple tasks such as sorting a list, to complex tasks such as playing a game of chess. Algorithms are also used in everyday life, such as when a person follows a recipe or drives to a destination. Algorithms help to make tasks easier and more efficient by breaking them down into smaller, manageable steps.
The information gain when splitting on a and b can be calculated by subtracting the entropy or gini index of the split from the entropy or gini index of the parent node. The attribute with the highest information gain would be chosen by the decision tree induction algorithm. The gain in the gini index when splitting on a and b can be calculated by subtracting the gini index of the split from the gini index of the parent node. The attribute with the highest gain in the gini index would be chosen by the decision tree induction algorithm. Yes, entropy and the gini index are both monotonously increasing on the range [0, 0.5] and monotonously decreasing on the range [0.5, 1].

1. Minimum Health Alex and Charlle are playing an online video game. Initially, there are m players in the first level, and there are next n levels. Each level introduces a new player (along with the players from the previous level). Each player has some strength which determines the difficulty of beating this player. To pass any level, select any available players and beat them. Alex has completed the game and beaten the rank th strongest player at every level. Now it's Charlie's turn to play. Whenever a player is beaten, Charlie's health decreases by the amount of strength of that player. So the initial health of Charlie must be greater than or equal to the sum of the strengths of players that are beaten throughout the game. Charlie does not want to lose to Alex, so Charlie decided to also beat the rank th strongest player at each level. What is the minimum initial health that Charlie needs to start with in order to do this? Example initlal, players =[1,2], new_players =[3,4], rank =2 Charlie needs to beat the 2nd strongest player at each level. For the first level, players have strengths 1 and 2 , so Charlie needs to beat the player with Charlie needs to beat the 2nd strongest player at each level. For the first level, players have strengths 1 and 2, so Charlie needs to beat the player with strength 1. For the second level, strengths are1, 2, and 3, so Charlie defeats strength 2. For the third level, strengths are 1, 2,3, and 4, so Charlie defeats strength 3 . Total health needed =1+2+3=6. Function Description Complete the function getMinimumHealth in the editor below. getMinimumHealth has the following parameter(s): int inital_players[ m] : the strength of initial m players of the game int new_players [n] : the strength of new n players that appear one by one after the first level int rank the rank that p2 needs to beat at every level Returns long: the initial health needed Constraints - 1≤n,m≤105
The minimum initial health that Charlie needs to start with in order to do that can be calculated using function MinimumHealth can be done using python programming language.

#Create / declare function MinimumHealth
def MinimumHealth(health, n) :

2. Busy intersection There is a busy intersection between two one-way streets: Main Street and 1st Avenue. Cars passing through the intersection can only pass through one at a time. When multiple cars arrive at the intersection at the same time, two queues can build up - one for each street. Cars are added to the queue in the order at which they arrive. Unfortunately, there is no traffic light to help control traffic when multiple cars arrive at the same time. So, the local residents have devised their own system for determining which car has priority to pass through the intersection: - If in the previous second, no car passed through the intersection, then the first car in the queue for 1 st Avenue goes first. - If in the previous second, a car passed through the intersection on 1st Avenue, then the first car in the queue for
1st
Avenue goes first. - If in the previous second, a car passed through the intersection on Main Street, then the first car in the queue for Main Street goest first.

You are asked to build a simple inventory management system for storing and updating information about a company's products. To simplify, assume that this company has only three products. For each product, the system stores a record about its inventory level (number of items) and the price of each item. Note that this information will need to be initialized before running the program.
There are three main operations provided by the system (listed below). When the system is started, the program should list these three operations and let the users choose which one to execute. These functionalities are as follows:
1) Generate overall statistics for the entire inventory (total number of items, average price per item, the minimum number of items among the products and the maximum number of items among the products).
2) Retrieve information (quantity or price) for a given product
3) Update information (quantity or price) for a given product
Once the user makes a selection, the program should invoke a relevant function and complete the operation. The system should continue running (i.e., functionality selection should be provided to the user repeatedly) until the user kills the execution of the program (possibly with a unique input character). One possible system design could have four functions:
Function 1: display_system_operations
Inputs: None
Outputs: None
Description: This function prints out all possible operations of the system for the user to choose.
Function 2: generate_overall_stats
Inputs: None
Outputs: Print overall statistics
Description: This function generates all basic statistics of all products, such as the total number of items, average price per item, the minimum number of items among the products and the maximum number of items among the products.
Function 3: retrieve_information
Inputs: product name and information type (quantity or price or both)
Outputs: Print the information requested
Description: This function retrieves the relevant information for a given product, which is obtained from the user as an input.
Function 4: update_information
Inputs: product name, information type (quantity or price) and the updated quantity or price
Outputs: None
Description: This function updates the quantity or price information in the inventory.
Hints:
1) You can initialize the product quantities and the prices using lists. For indexing the products, you can use a list of lists.
2) Remember that lists can be modified directly; the important thing is to identify the correct indices based on user input.
3) You can use formatting options (the format method) to print out nicer looking outputs.
4) You can design a main function which will be the starting point when you execute the entire program. Main function is also a function like others.
