\nYou are given the following:\n\n*  A sentence S1\n*  A string S2\n*  A character C that can be either \'Y or \'N\n*  An integer l\n\nA Hack number is defined as follows:\n\n\u2022 It is the first occurrence (the index of the first character) of string S2 in sentence S1 starting from the initial position l or occurring at later positions after I depending on the value of C.\n\n. If C is \'Y, then the matched string S2 must have a space to the left of it in sentence S1 or should be at the start of S1. It contains a space to the right of it in S1 or should be at the end of S1. In other words, the matched string must be an independent word in sentence S1.\n\nIf C is \'N, then there are no such conditions and it can also be inside any word of S1. Refer to the sample test case 2 and 3 as an example.\n\n\u2022 If no element in S1 matches any element in S2 after the given position l, then print \'Goodbye Watson\' without quotes.\n\nReturn the hack number
