Next Greater Frequency

Given an array of integers, find the next greater frequency for each unique number. The frequency is defined as the number of times a number appears in the array. For each number in the array, you should return the first number that has a higher frequency than it. If no such number exists, return -1 for that number. Print the results in the order of the original array. Example: Input: 5 3 1 3 2 1 2 1 Output: 3 -1 3 -1 -1 2 2 -1 Input format: A single line containing space-separated integers for the array. Output format: A single line containing space-separated integers, representing the next greater frequency for each corresponding number.
