给定一个含有 n 个正整数的数组和一个正整数 s , 找到一个最小的连续子数组的长度,使得这个子数组的数字和 ≥  s .如果不存在符合条件的子数组,返回 0.举个例子,给定数组 [2,3,1,2,4,3] 和 s = 7,子数组 [4,3]为符合问题要求的最小长度.更多练习:如果你找到了O(n) 解法, 请尝试另一个时间复杂度为O(n log n)的解法. 详见:https://leetcode.com/problems/minimum-size-subarray-sum/descriptio…

Minimum Size Subarray Sum Given an array of n positive integers and a positive integer s, find the minimal length of a contiguous subarray of which the sum ≥ s. If there isn't one, return 0 instead. Example: Input: s = 7, nums = [2,3,1,2,4,3] Output:…

1. 题目描述 给定一个含有 n 个正整数的数组和一个正整数 s ,找出该数组中满足其和 ≥ s 的长度最小的连续子数组.如果不存在符合条件的连续子数组,返回 0. 示例: 输入: s = 7, nums = [2,3,1,2,4,3] 输出: 2 解释: 子数组 [4,3] 是该条件下的长度最小的连续子数组. 2. 思路 双指针法.i和j指针分别是连续数组的两端.如果这个数组的值大于等于s则左指针+1,否则右指针+1. 3. 解法 class Solution: def minSubArray…

要求 给定一个含有 n 个正整数的数组和一个正整数 s 找出该数组中满足其和 ≥ s 的长度最小的连续子数组 如果不存在符合条件的连续子数组,返回 0 示例 输入:s = 7, nums = [2,3,1,2,4,3] 输出:2 解释:子数组 [4,3] 是该条件下的长度最小的连续子数组 思路 暴力解法(n3) 滑动窗口(时间n,空间1) 双索引,nums[l...r] 为滑动窗口 小于s,j后移 大于等于s,i后移 每次移动后,若大于等于s,则更新最小长度res L9:处理右边界到头的情况 1…
