Sum of Lengths of Non-Overlapping SubArrays
Easy Accuracy: 44.42% Submissions: 862 Points: 2

Given an array arr[] of N elements, the task is to find the maximum sum of lengths of all non-overlapping subarrays with K as the maximum element in the subarray.

Example 1:

Input: N = 9, K = 4
arr[] = {2, 1, 4, 9, 2, 3, 8, 3, 4} 
Output: 5
Explanation: {2, 1, 4} => Length = 3
             {3, 4} => Length = 2
             So, 3 + 2 = 5 is the answer.


Example 2:

Input: N = 7, K = 4
arr[] = {1, 2, 3, 2, 3, 4, 1} 
Output:  7
Explanation: {1, 2, 3, 2, 3, 4, 1} 
             => Length = 7.

 

Your Task:
This is a function problem. You don't need to take any input, as it is already accomplished by the driver code. You just need to complete the function calculateMaxSumLength() that takes array arr, integer N, and integeras parameters and returns the sum of the length of all such subarrays.

 

Expected Time Complexity: O(N). 
Expected Auxiliary Space: O(1).

 

Constraints:
1 ≤ N ≤ 106
