Describe a dynamic programming approach for a modified knapsack problem in which up to 3 copies of each of the n items can be selected

write the following usong for loops

Using Dr Racket, write a tail recursive function called popadd that models a population with P people at time t = 0 and adds d people per year

write a C++ program to Given a matrix of dimension m*n where each cell in the matrix can have values 0, 1 or 2 whichhas the following meaning:0: Empty cell1: Cells have fresh oranges2: Cells have rotten orangesSo we have to determine what is the minimum time required so that all the oranges becomerotten. A rotten orange at index [i,j] can rot other fresh orange at indexes [i-1,j], [i+1,j], [i,j-1],[i,j+1] (up, down, left and right). If it is impossible to rot every orange then simply return -1.Examples:Input: arr[][C] = { {2, 1, 0, 2, 1},{1, 0, 1, 2, 1},{1, 0, 0, 2, 1}};Output:All oranges can become rotten in 2 time frames.Input: arr[][C] = { {2, 1, 0, 2, 1},Tahir Iqbal Department of Computer Sciences. BULC{0, 0, 1, 2, 1},{1, 0, 0, 2, 1}};Output:All oranges cannot be rotten.Below is algorithm.1) Create an empty Q.2) Find all rotten oranges and enqueue them to Q. Also enqueuea delimiter to indicate beginning of next time frame.3) While Q is not empty do following3.a) While delimiter in…

Write a java program that takes a matrix representing an undirected graph (connectivity matrix) and finds the minimum spanning tree (using kruskal's or prim's algo.) of that graph and then print it graphically ( Graphical user interface should be used)

There are ? tasks assigned to ? workers, and each worker can be assigned only one task. Each worker can complete any one of the tasks, but the time spent varies. Use the ant colony algorithm to find the best allocation scheme that minimizes the total time spent. Please write a program to solve the problem (with python/C/C++)
