o Restrictions: Do not import any modules other than math and check. - Do not use Python constructs from later modules (e.g. loops and lists) You may use any string methods Question Cyclic Shift Consider the string abcde. The cyclic shifts of this string are bcdea, cdeab, deabc, eabcd, and abcde. In general, the cyclic shifts of a string s are all the strings t for which there are strings a and b such that s-a+b and t-b+a. (Note that a and/or b could be empty.) Write a function contains_cyclic_shift that consumes strings s1 and s2 and returns True if s1 has a cyclic shift of s2 as a substring. Otherwise, it returns False. For example, contains_cyclic_shift ('abccdeababc', 'abcde') -> True and contains_cyclic_shift ('abcbdeababc, 'abcde') False
