Write a Java program to find the maximum sum of a contiguous subsequence from a given sequence of numbers a1, a2, a3, ... an. A subsequence of one element is also a continuous subsequence
Write a Java program to find the maximum sum of a contiguous subsequence from a given sequence of numbers a1, a2, a3, ... an. A subsequence of one element is also a continuous subsequence
Input:
You can assume that 1 ≤ n ≤ 5000 and -100000 ≤ ai ≤ 100000. Input numbers are separated by a space. Input 0 to exit.
Expected Output:
How many integers would you like to input?
5
Input the integers:
25 61 35 42 66
Maximum sum of the said contiguous subsequence:
229
import java.util.*;
public class Main {
public static void main(String [] args) {
Scanner s = new Scanner(System.in);
System.out.println("How many integers would you like to input?");
int n = s.nextInt();
int ans = -100000;
int acc = 0;
System.out.println("Input the integers:");
for (int i=0;i<n;i++) {
acc += s.nextInt();
ans = Math.max(ans, acc);
if (acc < 0) acc = 0;
}
System.out.println("Maximum sum of the said contiguous subsequence:");
System.out.println(ans);
}
}
Sample Output:

5
Input the integers:
25 61 35 42 66
