Answer 1

Required Answer:-

Question:

• Write a program to input a number and display if the first digit and last digit are same or not.

Solution:

Here comes the program.

1. In Java.

import java.util.*;

public class Number {

public static void main(String[] args) {

int n, x, y;

Scanner sc=new Scanner(System.in);

System.out.print("Enter a number: ");

n=sc.nextInt();

x=n%10;

while(n>=9)

n/=10;

y=n;

if(x==y)

System.out.println("First and last digit are same.");

else

System.out.println("First and last digit are different.");

sc.close();

}

}

2. In Python.

n=int(input("Enter a number: "))

x=n%10

while n>=9:

n//=10

y=n

if x==y:

print("First and last digit are same.")

else:

print("First and last digit are different.")

3. In C

#include <stdio.h>

int main() {

int n, x, y;

printf("Enter a number: ");

scanf("%d", &n);

x=n%10;

while (n >= 9)

n/=10;

y=n;

if(x==y)

printf("First and last digits are same.");

else

printf("First and last digits are different.");

return 0;

}

4. In C++

#include <iostream>

using namespace std;

int main() {

int n,x,y;

cout << "Enter a number: ";

cin >> n;

while(n >= 9)

n /= 10;

y=n;

if (x==y)

cout << "First and last digits are same.";

else

cout << "First and last digits are different.";

return 0;

}

Algorithm:

• START.
• Accept the number.
• Find the first and last digit.
• Check if they are equal or not.
• Display the result.
• STOP.
