How do you reverse and add a number until you get a palindrome?

How do you reverse and add a number until you get a palindrome?

Take number from the user, reverse it and add it to itself. If the sum is not a palindrome then repeat the procedure until you get a palindrome. In this particular case, we got a palindrome (497794) after 5th addition. This method gives palindrome in few steps for almost all of the integers.

What is it called when you reverse a number?

When you mix up two numbers and put the first where the second should go, this is an example of a time when you transpose the numbers.

How do you reverse the order of numbers in C?

Let’s see a simple c example to reverse a given number.

  1. #include
  2. int main()
  3. {
  4. int n, reverse=0, rem;
  5. printf(“Enter a number: “);
  6. scanf(“%d”, &n);
  7. while(n!=0)
  8. {

How to reverse and add until a palindrome?

Given a positive integer, reverse the digits and add the resulting number to the original number. How many times does one have to repeat the process until one gets a palindrome?

Is there a way to reverse digits and add?

The “reverse and add” method is simple: choose a number, reverse its digits and add it to the original. If the sum is not a palindrome (which means, it is not the same number from left to right and right to left), repeat this procedure.

What happens if the sum is not a palindrome?

If the sum is not a palindrome (which means, it is not the same number from left to right and right to left), repeat this procedure. In this particular case the palindrome 9339 appeared after the 4th addition. This method leads to palindromes in a few step for almost all of the integers.

How to calculate the palindrome of a line?

The first line will have a number N with the number of test cases, the next N lines will have a number P to compute its palindrome. For each of the N tests you will have to write a line with the following data : minimum number of iterations (additions) to get to the palindrome and the resulting palindrome itself separated by one space.
