Hi guys I'm studying AUTOMATA, I am having a really hard time with these two problems. How do I prove thiese two problems please?

Problems 1. Given an alphabet Y, an instance of the symbol find problem over Y consists of a string w over together with a single symbol E Y. The instance is true if and only if some symbol of the string w is equal to a. Prove that the symbol find problem over is in Nick's Class. 2. Prove that every regular language is in Nick's Class.
