Write the code for choosing the list of items in order to get the maximum profit of fractional knapsack problem. [NOTE: number of input items should be user interest, and output should be like - firstly print the resulting profit table, and then print the all selected items (must not be all items from the inputted items - means that all inputted items should not be as the selected items) for the knapsack and then print the maximum profit.]

Euclid’s method for finding the greatest common divisor (GCD) of two positive integers consists of the following steps:Step 1: Divide the larger number by the smaller and retain the remainder.Step 2: Divide the smaller number by the remainder, again retaining the remainder.Step 3: Continue dividing the previous remainder by the current remainder until the remainder is zero, at which point the last non-zero remainder is the GCD. For example, if the two positive integers are 84 and 49, you have the following: Step 1: 84/49 yields a remainder of 35.Step 2: 49/35 yields a remainder of 14.Step 3: 35/14 yields a remainder of 7.Step 3: 14/7 yields a remainder of 0. Therefore, the last non-zero remainder, which is 7, is the GCD of 84 and 49.Using Euclid’s algorithm, replace the stub function written for Exercise 14 with an actual function that determines and returns the GCD of its two integer arguments. thank you…arrow_forward
- Problem 2 (5 pts) Write a Python program that plays the game Ro-Sham-Bo (a.k.a., Rock, Paper, Scissors) for a player and a computer opponent. The player selects one of the options listed in a console prompt, then the computer randomly selects an option as well. The winner of the game is determined as follows: Rock beats Scissors - Scissors beats Paper - Paper beats Rock The same selection results in a tie. Your program must do the following: Prompt the player to enter a selection in the console. Provide instructions to user on what is a valid input. For example, you can have the integers 1, 2, and 3 represent the selection, or use the words rock, paper, scissors, etc. Check that the user entered valid input. If the entry is invalid, the program needs to inform the user of the invalid input and can end, or re-prompt the user for their entry. Generate a random selection for the computer's choice. You can use a random integer and follow the same rules as was stated to the user. - Display…arrow_forwardProblem 1 (Ransom Note Problem) in python A kidnapper kidnaps you and writes a ransom note. He does not write it by hand to avoid having his hand writing being recognized, so he uses a magazine to create a ransom note. We need to find out, given the ransom string and magazine string, is it possible to create a given ransom note. The kidnapper can use individual characters of words. Here is how your program should work to simulate the ransom problem: your program should prompt the user to enter a long String to represent the magazine and another short String to represent the required ransom note. your program needs to check if the magazine string contains all required characters in equal or greater number present in the ransom note. your program should print true if it is possible to create the given ransom note from the given magazine, and print false otherwise.

- 2, Towers of Hanoi Problem. (10 points) The Towers of Hanoi is a famous problem for studying recursion in computer science and searching in artificial intelligence. We start with N discs of varying sizes on a peg (stacked in order according to size), and two empty pegs. We are allowed to move a disc from one peg to another, but we are never allowed to move a larger disc on top of a smaller disc. The goal is to move all the discs to the rightmost peg (see figure). To solve the problem by using search methods, we need first formulate the problem. Supposing there are K pegs and N disk. Answer the following questions. (1) Determine a state representation for this problem. (4points) (2) What is the size of the state space? (3 points) (3) Supposing K=3, N=4, what is the start state by using your proposed state representation method and what is the goal state?
