C++ implementation to find subarray with given sum#include <bits/stdc++.h> using namespace std; vector<int> find(vector<int> a,int n,int s){ vector<int> b; //output vector int cur_sum=0; for(int i=0;i<n;i++){ cur_sum=a[i];//cur_suming element for(int j=i+1;j<n;j...
使用一个字典保存数组某个位置之前的数组和,然后遍历数组求和,这样当我们求到一个位置的和的时候,向前找sum-k是否在数组中,如果在的话,更新结果为之前的结果+1。同时,当前这个sum出现的次数就多了一次。 和560. Subarray Sum Equals K几乎一模一样的题目,为什么就是不会做呢? classSolution(object):defnumSubarr...
Minimum Size Subarray Sum (python 版) bofei yan 懒人 来自专栏 · python算法题笔记 Minimum Size Subarray Sum 解法: 从左至右遍历数组,做部分和 sn;开始阶段,如果 sn < target,sub_len(记录符合条件的子数组长度) 加1;如果 sn >= target,在满足条件的情况下,尝试剔除字串最左边 l 处数值,l 加1,su...
1.初始化求和sum,返回结果res,左边界index=0 2.移动右边界,sum累加计和 3.当sum < target,不断累加计和,重复步骤2 4.当sum >= target,考虑移动左边界,减小sum值,res取上步res及序列长度i-index+1的较小值 5.重复步骤4,直到sum < target,重复步骤3 6.遍历结束后,取到的res即为满足target计和的子序列...
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: Input: s = 7, nums = [2,3,1,2,4,3] ...
Given an array A of integers, return the number of (contiguous, non-empty) subarrays that have a sum divisible by K. Example 1: Input: A=[4,5,0,-2,-3,1], K=5 Output:7 Explanation: There are7subarrays with a sum divisible by K=5: ...
Given an array A of integers, return the number of (contiguous, non-empty) subarrays that have a sum divisible by K. Example 1: Note: 给定一个集合,求这个集合中子集的个数,其中对子集的要求是子集中元素的和能被k整除。 记数组pre[i+1]表示前 i 位元素的和mo...7...
Program to find expected sum of subarrays of a given array by performing some operations in Python JavaScript Return an array that contains all the strings appearing in all the subarrays Reduce a given array by replacing all subarrays with values less than a given number K by their sum Count...
Given an array of integers, the task is to find the maximum subarray sum possible of all the non-empty arrays. Input: [−2, 1, −3, 4, −1, 2, 1, −5, 4] Output: 6 Explanation: Subarray [4, −1, 2, 1] is the max sum contiguous subarray with a sum of 6. We ...
