   printf("Enter the number: ");
   scanf("%d", &n);
   
   while (n > 0)
   {
      sum = sum * 10 + n%10;

Q. Write an algorithm to Reverse Number.

1. Start
2. Initialize an integer variable `sum` to 0. This will hold the reversed number.
3. Read the input integer `n`.
4. While `n` is greater than 0, do the following:
   - Extract the last digit of `n` by computing `n % 10`.
   - Update `sum` by multiplying the current `sum` by 10 and adding the extracted digit.
   - Remove the last digit from `n` by dividing `n` by 10.
5. When `n` becomes 0, all digits have been processed.
6. Print the value of `sum`, which now contains the reversed number.
7. End
