The immediate higher number to the right of each element in an array
Iterate through the array from right to left
For each element, compare it with the elements to its right to find the immediate higher number
Store the immediate higher number in a new array
Count pairs in an array whose sum is a perfect square.
Iterate through the array and calculate the sum of each pair.
Check if the sum is a perfect square using a function.
