SOLUTION

elementary problem

Algorithm analysis

The last digit of a positive integer n is n % 10.

Algorithm implementation

Read the input value of n.

scanf("%d",&n);

Compute and print the last digit of the number n.

printf("%d\n",n % 10);

Java implementation

import java.util.*;

public class Main

{

public static void main(String[] args)

{

Scanner con = new Scanner(System.in);

int n = con.nextInt();

int res = n % 10;

System.out.print(res);

con.close();

}

}

Python implementation

Read the input value of n.

n = int(input())

Compute and print the last digit of the number n.

a = n % 10

print(a)
