Find the contiguous subarray within an array (containing at least one number) which has the largest sum. 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. View Code What if multiply?
#include<vector>#include<algorithm>usingnamespacestd;intmaxSubArray(vector<int>& nums){// 如果数组为空,直接返回0if(nums.empty())return0;intmaxSum = nums[0];// 初始化最大子数组和为数组的第一个元素intcurrentSum = nums[0];// 初始化当前最大子数组和为数组的第一个元素// 从数组的第二个...
In this tutorial, we will be discussing a program to find maximum subarray size, such that all subarrays of that size have sum less than k. For this we will be provided with an array of size N and an integer k. Our task is to find the length of subarray such that all the...
The maximum subarray problem is the task of finding the contiguous subarray within a one-dimensional array of numbers (containing at least one positive number) which has the largest sum. For example, for the sequence of values −2, 1, −3, 4, −1, 2, 1, −5, 4; the contiguous...

int max_cir = sum + maxSubArray(A); if(sum!=0&& max_cir == 0 ) return max_nor ; else if(max_cir> max_nor) return max_cir; else return max_nor; 同时这里为了防止 第二种情况 所有的元素都被舍弃。 if(sum!=0&& max_cir == 0 ) return max_nor ; ...
int max_sum = maxSubarraySum(arr, n); cout << "Maximum subarray sum is " << max_sum << endl; return 0; } 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 ...
Hello everyone, I would like to quickly compute maximum sum subarray with queries (changeith element tox). Can we do it faster thanO(log(n))per query? The answer is no, and here is the reasoning. You can answer this question using some logic by reducing the problem to a known one. ...
2. Once the sum has beens find, re-apply Kadane’s algorithm to find the maximum sum again with some minor changes) Example Live Demo #include <bits/stdc++.h> using namespace std; int getMaxSubarraySum(int *arr, int n){ int max = INT_MIN; int currentMax = 0; for (in...
Solving another classic: theMaximum sum sub-arrayproblem. I am amazed to find out how many of you guys have solved this question, but only so few know the approach using partial sums. This video is for you! Also, throwback to those amazing times I was shooting my "Bible of Coding Inter...
