kadane's algorithm 示例和证明(从5:31左右开始) 假设之前造成最大值的subarray是M,当for loop 开始循环后,每遇到一个值,我们判断是否要取X,即 max_current = max(num,max_current+num) 即当前在index nth时(截止到并包括X),当前造成最大值的subarray=max([X],[M,X]),也就是我们到底要不要之前的M。...
Kadane's Algorithm 的思想可以应用于许多不同的问题,如 Leetcode 的 918 和 978 题。尽管具体细节可能有所不同,但贪心的核心思想是一致的:丢弃对后续计算无益的部分。📚 总结 Kadane's Algorithm 是一种高效的贪心算法,用于在数组中找到最大子数组和。通过丢弃对后续计算无益的部分,算法的时间复杂度可以降低...
Kadane’s Algorithm 我们看LeetCode的53题 给定一个整数数组 nums ,找到一个具有最大和的连续子数组(子数组最少包含一个元素),返回其最大和。示例: 输入: [-2,1,-3,4,-1,2,1,-5,4], 输出: 6 解释: 连续子数组 [4,-1,2,1] 的和最大,为 6。 来源:力扣(LeetCode)链接:https://leetcode-...
Kadane 算法(Kadane’s algorithm)是一种用于解决最大子数组问题的动态规划算法。最大子数组问题的目标是在一个整数数组中找到一个连续的子数组,使得该子数组的和最大。 Kadane 算法的思路很简单:从头到尾遍历数组,用两个变量max_so_far和max_ending_here分别记录全局最大子数组的和以及当前最大子数组的和,每次...
Kadane’s Algorithm Kadane’s algorithm is an efficient algorithm used to find the maximum sum subarray within a given array of integers. It was proposed by computer scientist Jay Kadane in 1984. The algorithm works by maintaining two variables: "max_so_far" and "max_ending_here". "max_so...
