# Partition N into M parts such that difference between Max and Min part is smallest

Given two integers **N** and **M**, partition N into M integers such that the difference between the maximum and minimum integer obtained by the partition is as small as possible.

Print the M numbers **A1, A2….Am**, such that:

- sum(A) = N.
- max(A)-min(A) is minimized.

**Examples**:

Input: N = 11, M = 3Output: A[] = {4, 4, 3}Input: N = 8, M = 4Output: A[] = {2, 2, 2, 2}

To minimize the difference between the terms, we should have all of them as close to each other as possible. Let’s say, we could print any floating values instead of integers, the answer in that case would be 0 (print N/M M times). But since we need to print integers, we can divide it into 2 parts, floor(N/M) and floor(N/M)+1 which would give us the answer at most 1.

How many terms do we need to print of each type?

Let’s say we print **floor(N/M)** M times, the sum would be equal to **N – (N%M)**. So we need to choose **N%M** terms and increase it by 1.

Below is the implementation of the above approach:

**Output:**

**Time Complexity:** O(n + m), where n and m are the values of the given integers.**Auxiliary Space: **O(1), no extra space is required, so it is a constant.
