Max Element After Update Operations

Given an array A of size N, initialized with all zeros, and another array ARR of M pairs of integers representing operations. Each operation consists of a range where each element within that range in A is incremented by 1. The task is to find and return the maximum element in array A once all operations have been performed.

Input:

n = 5
operations = [ (1, 5), (2, 4) ]

Output:

2

Example:

Suppose ‘N’ is 5. Initially, the array A is [0, 0, 0, 0, 0].
Perform operation (1, 5), array becomes [1, 1, 1, 1, 1].
Next, perform operation (2, 4), array becomes [1, 2, 2, 2, 1].
The maximum element post operations is 2.

Constraints:

• 1 ≤ T ≤ 10
• 1 ≤ N ≤ 10^3
• 1 ≤ M ≤ 10^3
• 1 ≤ L ≤ N
• L ≤ R ≤ N
• Operations are based on 1-indexing.

Note:

You are not required to print anything; it has already been handled. Implement the function to return the result.
