Array Mean Decrement

You are given an array of integers. Your task is to find the minimum number of decrements needed to ensure that the mean of the array is less than or equal to a given threshold value t. A decrement means reducing an element by 1. Input: - The first line contains an integer n (1 <= n <= 1000), the number of elements in the array. - The second line contains n space-separated integers, the elements of the array. - The third line contains a float t (0 <= t <= 100). Output: - Print a single integer: the minimum number of decrements required to achieve the threshold mean. Example: Input: 4 10 20 30 40 25.0 Output: 45
