 Given a number N, the task is to check if N is a Leap Year or not. A leap year is exactly divisible by 4 except for century years (years ending with 00). The century year is a leap year only if it is perfectly divisible by 400. Code:

This a coding problem based on Caesar Cypher(or Cipher). Caesar Cipher Technique is a simple and easy method of encryption. It is a simple type of substitution cipher in which each letter of plain text is replaced by a letter with some fixed number of positions down with alphabet. This is used in a way: Given: a=z  b=y ............ z=a For example: Input: abc Output should Be:  zyx Code:

Our hoary culture had several great persons since time immemorial and king vikramaditya’s nava ratnas(nine gems) belongs to this ilk.
