Twitter | Coding Round | Array Game

I recently interviewed with Twitter for a coding position. The interview consisted of a coding round where I was presented with a problem involving an array of integers. The task was to find the minimum number of operations to make all elements of the array equal, where an operation involved incrementing n-1 elements by one. I approached the problem by first understanding that incrementing n-1 elements is mathematically equivalent to decrementing one element relative to the others. Thus, the problem effectively reduces to making all elements equal to the minimum element in the array by only decrementing. My solution involved sorting the array in descending order and then iterating through it to sum the necessary moves.
