👉 In computer programming, a "pre-averaging" operator is one that takes an input array and returns an output array where each element in the original array is averaged with all other elements to produce a new average. This concept is often used to improve performance by reducing the number of calculations required during the computation. For example, consider a 2D array of integers: ``` int[][] arr = {{1, 2}, {3, 4}, {5, 6}}; ``
