String Rotation Check

Given two non-empty strings s1 and s2, determine whether s2 is a rotation of s1. A string s2 is considered a rotation of s1 if it can be obtained by taking a contiguous part from the end of s1 and appending it to the beginning.

For example, if s1 = "waterbottle" then s2 = "erbottlewat" is a valid rotation. You are required to read the two strings from the standard input (each on a separate line) and print True if s2 is a rotation of s1 or False otherwise.

Note: The check is case-sensitive and the strings will only contain printable characters.

inputFormat

The input consists of exactly two lines:

1. The first line contains the string s1.
2. The second line contains the string s2.

Both strings are non-empty and may contain spaces.

outputFormat

Output a single line with either True or False (without quotes). Output True if s2 is a rotation of s1, and False otherwise.
