In this article, we'll explore multiple approaches to solving the problem of finding a subarray with a given sum in Java. Problem Statement Given an array of integers and a target sum, find a continuous subarray in the array that adds up to the given sum. The problem can be divided ...
A in the input array, n is the length of the array & s in the given sum. Initialize vector b. (for storing indexes of subarray) Initialize a variable cur_sum=0 for i=0:n-1 set cur_sum=A[i] for j=i+1:n-1 add A[j] to cur_sum if(cur_sum==s) i is the starting index...

1 class Solution { 2 public int minSubArrayLen(int s, int[] nums) { 3 return sub(0,s,nums);//开始寻找 4 } 5 public int sub(int i,int s,int[] nums)//i为当前其实坐标,s和值,nums数组 6 { 7 if(i>=nums.length) return 0;//当达到数组尾端返回0 8 int count=0,sum=0; 9 f...
209. Minimum Size Subarray Sum java solutions Given an array of n positive integers and a positive integer s, find the minimal length of a subarray of which the sum ≥ s. If there isn't one, return 0 instead. For example, given the array[2,3,1,2,4,3]ands = 7,...

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...
Java class Solution { public int numSubarraysWithSum(int[] A, int S) { if (A.length == 0) return 0; int result = 0; int[] sumOne = new int[A.length]; int st = 0; int ed = 0; sumOne[0] = A[0] == 1 ? 1 : 0; ...
Given an array of integers and an integer k, you need to find the total number of continuous subarrays whose sum equals to k. Example 1: Input:nums = [1,1,1], k = 2 Output: 2 Note: The length of the array is in range [1, 20,000]. ...
