Make all array elements equal by replacing adjacent pairs by their sum | Function to count the minimum number of pairs of adjacent elements required to be replaced by their sum to make all arrat elements equal.
Stores the prefix sum of the array.
Calculate the prefix sum array.
Stores the maximum number of subarrays into which the array can be split.
Iterate over all possible sums.
Traverse the array.
If the sum is equal to the current prefix sum.
Increment count of groups by 1.
Otherwise discard this subgroup sum.
Update the maximum this of subarrays.
Return the minimum number of operations.
