// 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
