For each of the following problems, decide whether it is NP-Complete or polynomial-time solvable and select the ones that are NP-complete: Does there exist a cycle that visits each vertex exactly once in a graph? Does there exist a cycle that visits each edge exactly once in a graph? Does there exist a cycle that visits each vertex and each edge exactly once in a graph? Does a graph contain a vertex cover of size at most 100? Does a tree on n nodes contain a clique of size k?
