Mean Rank Subarray Count

Problem Statement

Code Question 1 Amazon Academy recently organized a scholarship test on its platform. There are n students with roll numbers 1, 2, ..., n who appeared for the test, where the rank secured by the i th student is denoted by rank[i]. Thus, the array rank is a permutation of length n. Groups can only be formed with students having consecutive roll numbers, in other words, a subarray of the original array. For each value x (1 ≤ x ≤ n), find the number of groups that can be formed such that they have a mean rank equal to x. More formally, given a permutation of length n, find the number of subarrays of the given array having a mean value equal to x, for each x in the range [1, n]. Notes The mean value of an array of k elements is defined as the sum of elements divided by k. A permutation of length n is a sequence where each number from 1 to n appears exactly once. A subarray of an array is a contiguous section of the array. Function Description Complete the function getMeanRankCount with the
