What is the best case scenario? What is the exact number of operations for the best case scenario in terms of n and m? What is the big-oh for the best case scenario? What is the worst case scenario? What is the exact number of operations for the worst case scenario in terms of n and m? What is the big-oh for the worst case scenario? Consider the following algorithm that determines if two arrays have no elements in common. Assume that (a) the first array has n elements and the second array has m elements, and that (b) the comparison on line 3 is the operation that counts towards running time.
