2.Smallest Subarray with a given sum(easy) 2.1 问题描述 Given an array of positive integersnumsand a positive integertarget, return the minimal length of a「contiguous subarray」[numsl, numsl+1, ..., numsr-1, numsr]of which the sum is greater than or equal totarget. If there is no...

ineditorial. Then I came up with a different approach: we can iterate through the possible length of a subarray, pick one with the largest sum, update the answer. However, I don't know how to implement finding a subarray with length = 1..n and maximum sum fast enough to pass all ...
Given an array A of integers, return the number of (contiguous, non-empty) subarrays that have a sum divisible by K. Example 1: Input: A = [4,5,0,-2,-3,1], K = 5 Output: 7 Explanation: There are 7 subarrays with a sum divisible by K = 5: ...
Explanation: The given array is the same as example 1. We have the new array [1, 2, 3, 3, 4, 5, 6, 7, 9, 10]. The sum of the numbers from index le = 3 to ri = 4 is 3 + 3 = 6. 1. 2. 3. Example 3: Input: nums = [1,2,3,4], n = 4, left = 1, right...
