## Algorithm

1. Read the first number, let's call it `num1`.
2. Read the second number, let's call it `num2`.
3. Extract the last digit of `num1` using the modulo operator `%` with 10, and store it in a variable, let's call it `lastDigit1`.
4. Extract the last digit of `num2` using the modulo operator `%` with 10, and store it in a variable, let's call it `lastDigit2`.
5. Compare `lastDigit1` with `lastDigit2`.
6. If they are equal, print or return "The numbers have the same last digit."
7. If they are not equal, print or return "The numbers do not have the same last digit."

## Code Examples

### #1 Code Example- Check the Last Digit

```Code - Javascript Programming```

``````/* program to check whether the last digit of three
numbers is same */

// take input
const a = prompt('Enter a first integer: ');
const b = prompt('Enter a second integer: ');
const c = prompt('Enter a third integer: ');

// find the last digit
const result1 = a % 10;
const result2 = b % 10;
const result3 = c % 10;

// compare the last digits
if(result1 == result2 && result1 == result3) {
console.log(`\${a}, \${b} and \${c} have the same last digit.`);
}
else {
console.log(`\${a}, \${b} and \${c} have different last digit.`);
}``````

Output

cmd
Enter a first integer: 8
Enter a second integer: 38
Enter a third integer: 88
8, 38 and 88 have the same last digit.
