Question
C code for this problem:
![Mr. A really likes palindromes, so he is always looking for character strings that include palindromes. One day he realized
that since pi is an infinite sequence, it might contain a lot of palindromes, and this inspired him to look for palindromes in
large number sequences. As it is not possible to do so manually, he created a program to output the longest palindrome
from an input sequence.
The mission
Build a program to output the longest palindrome from an input number.
What is a palindrome?
A palindrome is a sequence that reads the same backwards as forwards, e.g. madam, 1, 22, 1234321. You can check if
a string A is a palindrome or not by using the pseudo code below.
A == reverse(A)

Input rules
• The CLI application does not accept arguments.
• A string consisting of numbers between 0 and 9 is given as standard input.
• The length of the string is 1 million or less.
Output rules
• The longest palindrome from an input number is output.
• If there are multiple longest palindromes available, the first one is output as the longest palindrome.
