4. Consider the following function definition: F:S Z+ The set S is the set of all strings containing x's and y's. The function F is defined as follows for each s ES (s is a string): = the number of x's in s F(s) = Is the function injective? Is the function surjective? For each case, either prove your answer or provide a counterexample
