题目地址: https://leetcode.com/problems/maximum-subarray/description/ 题目描述: 经典的求最大连续子数组之和. 解法: 遍历这个vector,每次循环累加当前数值,同时更新最大值,若当前的累加和是负数,需要更新为0,因为在进行下一次累加求和的时候, 无论下一个数是正还是负,加上上一次的为负的和,都将变得更小,因而下一次求和时直接从当前值开始计算. 代码: class Solution { public: int maxSubArray…

53. Maximum Subarray 之前的值小于0就不加了.dp[i]表示以i结尾当前的最大和,所以需要用一个变量保存最大值. 动态规划的方法: class Solution { public: int maxSubArray(vector<int>& nums) { vector<int> dp(nums.size()); int res = INT_MIN; ;i < nums.size();i++){ dp[i] = nums[i]; &&…

题目描述 给定一个序列(至少含有 1 个数),从该序列中寻找一个连续的子序列,使得子序列的和最大. 例如,给定序列 [-2,1,-3,4,-1,2,1,-5,4], 连续子序列 [4,-1,2,1] 的和最大,为 6. 扩展练习: 若你已实现复杂度为 O(n) 的解法,尝试使用更为精妙的分治法求解. 思路 思路一: maxSum 必然是以numsi结尾的某段构成的,也就是说maxSum的candidate必然是以nums[i]结果的.如果遍历每个candidate,然后进行比较,那么就能找到最大…
