This is a simpler version of LeetCode 862 Shortest Subarray with Sum at Least K. Each element is > 0. Both the binary search and deque solution work. However, because we only have positive integers in the input, we can further simplify the solution by using sliding window + two pointers....
Given an array of integers A, find the sum of min(B), where B ranges over every (contiguous) subarray of A. Since the answer may be large, return the answer modulo 10^9 + 7. Example 1: Input: [3,1,2,4] Output: 17 Explanation: Subarrays are [3], [1], [2], [4], [3,...
Maximum Sum Subarray of Size K (easy) /* Given an array nums and a target value k, find the maximum length of a subarray that sums to k. If there isn't one, return 0 instead. Note: The sum of the entire nums array is guaranteed to f......
