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 integer** K **as 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 ≤ 10^{6}
