Hello Codeforces. Recently I faced a problem which I couldn't solve in an hour. It is as follows: Max Sum Subarray of atleast 2 numbers. Of course, for just max sum subarray it is Kadane's algorithm in O(n) time
这个问题是这样的(https://leetcode.com/problems/maximum-subarray/): Given an integer array nums, find the contiguous subarray (containing at least one number) which has the largest sum and return its sum. 就是给一组整数,找到一组连续的子序列,让子序列的和最大,并且返回最大和。 比如说: 输入...

For example, given the array[−2,1,−3,4,−1,2,1,−5,4], the contiguous subarray[4,−1,2,1]has the largest sum =6. A[i]有两种选择 1.新开一个数组; 2.加入原有数组max +a[i]; publicclassSolution {publicintmaxSubArray(int[] A) {intmax_here=A[0];intmax_sofar=A[0...
Algo: maxSubArray vs. maxProduct 这两个问题类似,都可利用动态规划思想求解。 一、最大连续子序列和 https://leetcode.com/problems/maximum-subarray/description/ https://www.geeksforgeeks.org/largest-sum-contiguous-subarray/ The core ideas are the same:...

选择排序是一种简单直观的排序算法,其基本思想是每次从待排序的数据中选择最小(或最大)的元素,放到已排序序列的末尾(或开头),直到所有元素都排序完成。 在Python中,可以使用Min和Max函数来实现从两端进行选择排序。具体步骤如下: 定义一个待排序的列表。 初始化两个指针,一个指向列表的开头,一个指向列表的末尾。
