<编程之美>183页,问题2.14——求子数组的字数组之和的最大值.(整数数组) 我开始以为可以从数组中随意抽调元素组成子数组,于是就有了一种想法,把最大的元素抽出来,判断是大于0还是小于等于0,如果大于0就对除了这个最大值外剩下的数组部分进行递归: using System; using System.Collections.Generic; using System.Linq; namespace MaxSumSubArray { class Program { static void M…
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 0 instead. For example, given the array [2,3,1,2,4,3] and s = 7,the subarray [4,3] has the minimal…
题意 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 0 instead. For example, given the array [2,3,1,2,4,3] and s = 7, the subarray [4,3] has the mini…
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 subarr…
