LintCode 406: Minimum Size 题目描述 给定一个由 n 个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. 样例 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. Thu Feb 23 2017 思路 数组的题一般都是用指针扫描的. 这里是用一前一后两个指针都从左往右移,前面的指针一直移直到和大于s为止:后面的指针此时一直右移,直到距离最短为止. 时间复杂度是\(O(…

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,…

leetcode面试准备:Minimum Size Subarray Sum 1 题目 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] a…

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…

［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…

Given an integer array (index from 0 to n-1, where n is the size of this array), and an query list. Each query has two integers [start, end]. For each query, calculate the minimum number between index start and end in the given array, return the resu…

题目: 最小子数组 给定一个整数数组,找到一个具有最小和的子数组.返回其最小和. 样例 给出数组[1, -1, -2, 1],返回 -3 注意 子数组最少包含一个数字 解题: 和最大子数组 ,差不多的,动态规划的还是可以继续用的 Java程序: public class Solution { /** * @param nums: a list of integers * @return: A integer indicate the sum of minimum subarray */ publ…
