Given two integers M and N, the task is to create a list of M non-negative integers whose sum is N. In case when more than one list is possible, find any one.
Input: M = 4, N = 8
Output: 1 3 3 1
1 + 3 + 3 + 1 = 8
Input: M = 5, N = 3
Output: 0 1 1 0 1
Approach: To get a complete random list of integers, create an array of size M where every element is initialised with 0. Now run a loop from 0 to N – 1 and increment any randomly chosen element from the array by 1 using the rand() function. This way, sum of the resuntant list will be N.
Below is the implementation of the above approach:
1 3 3 1
