The round was completely based on problem solving with data structures and algorithms
1. Maximum Subarray Sum
Moderate
0/80
Asked in companies
You are given an array/list ARR consisting of N integers. Your task is to find the maximum possible sum of a non-empty subarray(contiguous) of this array.
Note: An array C is a subarray of array D if it can be obtained by deletion of several elements(possibly zero) from the beginning and the end of array D.
For e.g.- All the non-empty subarrays of array [1,2,3] are [1], [2], [3], [1,2], [2,3], [1,2,3].
Problem approach
import java.util.*;
public class Adarsh
{
public static int maxSum(int arr[],int n,int k)
{
//k must be greater
if(n {
System.out.println("Invalid");
return -1;
}
//compute sum of first window of size k
int res = 0;
for(int i=0;i res+= arr[i];
int curr_sum = res;
for(int i=k;i {
curr_sum += arr[i] - arr[i-k];
res = Math.max(res,curr_sum);
}
return res;
}
public static void main(String[] args)
{
int arr[] = {2, 3, 4, 1, 5};
int k =2;
int n = arr.length;
System.out.println(maxSum(arr, n ,k));
}
