Problem 1. Consider the list of tokens T1 = { "supper", "abcdle" } T2 = { "abd" } SUPPERID = strings that are ID (see below) and that have “supper” as prefix. For example, “supper123”, “supper”, “supperabc” are SUPPERID, but “supper_” is not SUPPERID because "supper_" is not an ID " " 11 ID = Set of strings that consist of a letter or underscore that is followed by zero or more letters and/or digits. For example, ‘_11”, “_1alb” are IDs, but "_ and "a_" are not IDs according to this definition CRAZYID = Set of strings that consist of an ID followed by "_crazy". For example, "a_crazy" is a CRAZYID, but “a_CRAZY", "acrazy" and "a_crazy" (two underscores) are not a CRAZYID NUM=Set of strings that consist of a non-zero digit that is followed by 1 or more digits or the string "0". For this problem, when identifying tokens in the input, we treat & and ! as separators. This means that getToken() should stop when it reaches & or ! and returns the longest matching prefix up to but not including the separator. The separator itself (& or !) cannot be part of a token, so the next token starts after the separators. & and ! are the only separator. Space characters are not separators for this problem. Consider the input: supper22 crazyabc!!&d1_11&_supper_11&123abcdle and the following sequence of calls: t1 = lexer.GetToken(); t2 = lexer.GetToken(); t3 = lexer.peek(1); t4 = lexer.peek(3); t5 = lexer.peek(5); t6 = lexer.peek(7); t7=lexer.GetToken(); t8 = lexer.GetToken(); What are the values of t1, t2, t3, t4, t5, t6, t7 and t8? You are only asked to give the values and not to explain how you obtained them.

Solved: Problem 1. Consider the list of tokens T1 = { "supper", "abcdle" } T2
