Was looking for a list of prefix sum problems to practice with and couldn\'t find a curated list. Here is one: \n\n[maximum-sum-of-3-non-overlapping-subarray](https://leetcode.com/problems/maximum-sum-of-3-non-overlapping-subarrays/) \n[continuous-subarray-sum](https://leetcode.com/problems/continuous-subarray-sum/)\n[subarray-sum-equals-k](https://leetcode.com/problems/subarray-sum-equals-k/)\n[maximum-size-subarray-sum-equals-k](https://leetcode.com/problems/maximum-size-subarray-sum-equals-k/)\n[number-of-submatrices-that-sum-to-target](https://leetcode.com/problems/number-of-submatrices-that-sum-to-target/)\n[max-sum-of-rectangle-no-larger-than-k](https://leetcode.com/problems/max-sum-of-rectangle-no-larger-than-k/)\n[binary-subarrays-with-sum](https://leetcode.com/problems/binary-subarrays-with-sum/)\n[path-sum-iii](https://leetcode.com/problems/path-sum-iii/)\n[subarray-sums-divisible-by-k](https://leetcode.com/problems/subarray-sums-divisible-by-k/)\n[range-sum-query-2d-immutable](https://leetcode.com/problems/range-sum-query-2d-immutable/)\n[count-number-of-nice-subarrays](https://leetcode.com/problems/count-number-of-nice-subarrays/)\n[matrix-block-sum](https://leetcode.com/problems/matrix-block-sum/)\n\n\nList: https://leetcode.com/list/xcgv5k25/ (thanks @wysohn2012)\n\nPlease post anything problems I missed and I will update. \n\nCheers!
