String is Rotated

Problem Description​

Write a function that accepts two strings and returns true if one string is a rotation of the other, taking letter case into account.

Tip: A string rotation is when you take a string, remove some letters from its end, then append them to the front. For example, “swift” rotated by two characters would be “ftswi”.

Input​

  • Two strings.

Output​

  • A boolean value: true if one string is a rotation of the other, false otherwise.

Constraints​

  • The function should consider letter case (e.g., 'A' is different from 'a').

Example​

Input:
"abcde"
"eabcd"

Output:
true

Explanation:
The string "eabcd" is a rotation of "abcde" by one character.

Input:
"abcde"
"cdeab"

Output:
true

Explanation:
The string "cdeab" is a rotation of "abcde" by three characters.

Input:
"abcde"
"abced"

Output:
false

Explanation:
The string "abced" is not a rotation of "abcde".

Input:
"abc"
"a"

Output:
false

Explanation:
The strings "abc" and "a" do not have the same length, so one cannot be a rotation of the other.
