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: 2 Explanation: the subar…

Given an array of n positive integers and a positive integer s, find the minimal length of a subarray of which the sum ≥ s. If there isn't one, return -1 instead. Have you met this question in a real interview?     Example Given the array [2,3,1,2,4,…

［抄题］: 给定一个由 n 个正整数组成的数组和一个正整数 s ,请找出该数组中满足其和 ≥ s 的最小长度子数组.如果无解,则返回 -1. 给定数组 [2,3,1,2,4,3] 和 s = 7, 子数组 [4,3] 是该条件下的最小长度子数组. [暴力解法]: 时间分析: 空间分析: ［思维问题］: 和 ≥ s 的最小长度子数组,和<s时j++,达到后更新j-i.再扫更大,所以此处打止.(j不用回去,否则会变成原来的i) 比小时,初始化为Integer.MAX_VALUE,忘了. ［一句话思路…
