There will be an array of elements. Add each digit of element and print the sum of each element.
Input:

11
Expected Output:

I am getting output as 5,2,0,0. How can i solve this?

What I have tried:

Java

import java.util.Scanner;
public class Main
{
	public static void main(String[] args) {
    	Scanner sc=new Scanner(System.in);
    	int n=sc.nextInt();
    	int a[]=new int[n];
    	for(int i=0;i<n;i++){
            a[i]="sc.nextInt();
        }
        int sum=0;
        for(int i=0;i<n;i++){
            for (int j=0;j<n;j++){
                while(a[j]>0){
    	            int d=a[j]%10;
    	            sum=sum+d;
    	            a[j]=a[j]/10;
    	        }
                System.out.println(sum);
                sum=0;
    	    }
    	}
    }
}

Solution 1

You have an extra for loop at:

Java

for(int i=0;i<n;i++){
    for (int j=0;j<n;j++){

Remove the first one and it should work correctly.

Obviously, you do not understand the logic of your code. Use the debugger to see what is going on.

Your code do not behave the way you expect, or you don't understand why !

There is an almost universal solution: Run your code on debugger step by step, inspect variables.
The debugger is here to show you what your code is doing and your task is to compare with what it should do.
There is no magic in the debugger, it don't know what your code is supposed to do, it don't find bugs, it just help you to by showing you what is going on. When the code don't do what is expected, you are close to a bug.
To see what your code is doing: Just set a breakpoint and see your code performing, the debugger allow you to execute lines 1 by 1 and to inspect variables as it execute.
