Shift Characters

You are given a string consisting of lowercase English letters. Your task is to shift each letter in the string by 3 positions forward in the alphabet. If the shift moves past 'z', it wraps around to the beginning (i.e. 'x' becomes 'a', 'y' becomes 'b', 'z' becomes 'c').

For example:

• The string "abc" becomes "def".
• The string "xyz" becomes "abc".

Read the input from standard input (stdin) and output the result to standard output (stdout).

inputFormat
