Version 2,采用动态规划求解,首先定义状态,dp[i]是以nums[i]为结尾的连续子数组的最大和,状态转移方程为:如果dp[i-1]>0,无论nums[i]是什么数,以nums[i]为结尾的连续子数组的最大和都为dp[i-1]+nums[i],如果dp[i-1]<0,无论nums[i]是什么数,以nums[i]为结尾的连续子数组的最大和都为nums[i]...
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: s = 7, nums = [2,3,1,2,4,3] [4,3] Follow up: If you have figured out the O(n) ...
