The prefix sum approach is an efficient way to calculate the sum of subarrays, and it can be contrasted with the naive approach which uses three nested loops.

The prefix sum approach is particularly useful when you have to perform many subarray sum queries on an unchanging array. After the single preprocessing step, each sum query takes constant time, which is a significant improvement over the naive approach's O(n^3) time complexity for calculating all subarray sums.
