Output Format

For each test case, display the sum of first and last digits of N in a new line.

Constraints

• 1 <= T <= 1000
• 1 <= N <= 1000000

Solution in Java:

import java.util.*;
import java.lang.*;
import java.io.*;

class Codechef
{
	public static void main (String[] args) throws java.lang.Exception
	{
	  Scanner sc = new Scanner(System.in);
	  
	  int T = sc.nextInt();
	  
	  while( T-- > 0){
	      int l = sc.nextInt();
	      int sum = l % 10;
	      int rem = 0;
	      while(l != 0) {
	          rem = l % 10;
	          l = l/ 10;
	      }
	      sum += rem;
	      System.out.println(sum);
	  }
	}
