Problem Statement for "InfiniteString"

Problem Statement

Given a string s, let f(s) denote the infinite string obtained by concatenating infinitely many copies of s. For example, if s = "abc" then f(s) = "abcabcabcabc...".

Note that the string f(s) still has a beginning. Hence, f("abc") and f("bca") are two different infinite strings: the first one starts with an 'a' while the other starts with a 'b'.

Sometimes, two different finite strings can produce the same infinite string. For example, f("abc") is the same as f("abcabc").

You are given Strings s and t. Check whether f(s) equals f(t). If the two infinite strings are equal, return "Equal". Otherwise, return "Not equal".
