Identify Palindrome

Problem Statement-: 

For a given positive number num, identify the palindrome formed by performing the following operations-

Add num and its reverse 

Check whether the sum is palindrome or not. If not, add the sum and its reverse and repeat the process until a palindrome is obtained 

For example: 

If original integer is 195, we get 9,339 as the resulting palindrome after the fourth addition: 

   195

+ 591

————–

   786

+ 687

————–

   1473

+ 3741

————–

   5214

+ 4125

———-

  9339

Input format: 

Read num from the standard input stream. 

Output format: 

Print the palindrome calculated to the standard output stream. 

Sample Test Cases

Sample Input 1
124

Sample Output 1
545

Explanation 1
The sum of 124 and its reverse 421 is 545 which is a palindrome. 

Sample input 1
4

Sample output 1
8

Explanation 1
The sum of 4 and its reverse 4 is 8 which is a palindrome.

 

Program :

def isPalindrome(n):

    return str(n)[::-1]==str(n)

def rev(n):

    return int(str(n)[::-1])

n=int(input("Number : "))

while(1):

    n=n+rev(n)

    if(isPalindrome(n)):

        print(n)

        break
