+Make Palindrome
+Given a string S of length l and you have to covert that into palindrome using the same string. You will 
+also given a number N, if N is 0 you have a make the palindrome of length 2xl, if N is 1 then the final 
+length will be 2xl - 1.
+
+A string is said to be a palindrome if the string read from left to right is equal to the string read 
+from right to left.
+
+If the length of the given string is 1, you don't have to do anything, just return the string. As every 
+letter is a palindrome of length 1.
