The right way to Verify for All Inclusive in C

The problem Enter:
a string strng an array of strings arr Output of operate contain_all_rots(strng, arr) (or containAllRots or contain-all-rots):
a boolean true if all rotations of strng are included in arr false in any other case Examples:
contain_all_rots( "bsjq", ["bsjq", "qbsj", "sjqb", "twZNsslC", "jqbs"]) -> true contain_all_rots( "Ajylvpy", ["Ajylvpy", "ylvpyAj", "jylvpyA", "lvpyAjy", "pyAjylv", "vpyAjyl", "ipywee"]) -> false) Notice:
Although not appropriate in a mathematical sense
we’ll contemplate that there are not any rotations of strng == "" and for any array arr: contain_all_rots("", arr) –> true The answer in C Possibility 1:
