Given three integers **N, K and S**, the task is to choose an array of size **N** such that there exists exactly **K** sub-arrays with sum **S**.**Note:** There can be many solution arrays to this problem.**Examples:**

Input:N = 4, K = 2, S = 3Output:1 2 3 4Explanation:

One of the possible array is [ 1, 2, 3, 4 ]

There exist exactly two subarrays with sum 3

Subarrays with Sum(3) = [ [ 1, 2 ], [ 3 ] ]Input:N = 5, K = 3, S = 50Output:25 25 25 10 40Explanation:

One of the possible array is [ 25, 25, 25, 10, 40 ]

There exist exactly three subarrays with sum 50

Subarrays with Sum(50) = [ [ 25, 25 ], [ 25, 25 ], [ 10, 40 ] ]

**Approach:**

One of the Solution Array for this problem contains **S** element **K** times and **S+1** element **(N-K)** times, to form K Sub-arrays of exactly one element with S as sum. If we combine any two or more elements of the array then it will give sum greater than S.

Below is the implementation of the above approach:
