Largest palindromic number in an array | Function to check if n is palindrome.
Find the appropriate divisor to extract the leading digit.
If first and last digits are not same then return false.
Removing the leading and trailing digits from the number.
Reducing divisor by a factor of 2 as 2 digits are dropped.
Function to find the largest palindromic number.
Sort the array.
If number is palindrome.
If no palindromic number found.
Driver Code.
