ogram which replaces each character in s by the character which is at a distance of move ahead, if move is positive. If move is 0 the original string is returned unchanged. If move is negative, then each character is replaced by a character at a distance move behind it. For example: When s=�ABCXYX�, encodeDecode(2) returns �CDEZAB� and When s=�ABCDE�, encodeDecode(-3) returns �XYZAB� [ICSE Sample Paper-2005]

A palindrome number is one that reads same from left to right or right to left. There is an ingenious method to get a palindrome from any positive integer. The procedure is as follows: Start with any positive number of 2 or more digits. Obtain another positive number by reversing the digits of the starting number. Add the two numbers together. Repeat the whole procedure with the sum as the starting number till you get a sum which is a palindrome number. // Program to calculate the palindrome of a given number in maximum 15 terms. Assu
