Statement
Implement a nextGreaterElement() function that takes an array of integers, arr, as input and returns the next greater number for every element in the array.
The next greater number for a number arr[i] is the first number to its right that is greater than arr[i]. If no such number exists, return -1 for this number.
Constraints:
-
arr.length
