DESCRIPTION:
Input:
a string strng an array of strings arr Output of function contain_all_rots(strng, arr) (or containAllRots or contain-all-rots):
a boolean true if all rotations of strng are included in arr false otherwise Examples:
contain_all_rots(
"bsjq", ["bsjq", "qbsj", "sjqb", "twZNsslC", "jqbs"]) -> true
contain_all_rots(
"Ajylvpy", ["Ajylvpy", "ylvpyAj", "jylvpyA", "lvpyAjy", "pyAjylv", "vpyAjyl", "ipywee"]) -> false)
Note:
Though not correct in a mathematical sense
we will consider that there are no rotations of strng == "" and for any array arr: contain_all_rots("", arr) --> true
