(a) Binary search def binary_search(sequence, start, end, key): if end return

(a) Binary search def binary_search(sequence, start, end, key): if end return False middle = (end + start) //2 if sequence [ middle] = key: return True elif sequence [ middle] > key: return binary_search(sequence, start, middle - 1, key) else: return binary_search(sequence, middle +1, end, key) (b) Merge sort Give 6 recurrences for the worst-case running times of each of the two algorithms above when arrays are passed using each of the three parameter-passing strategies above. Solve your recurrences giving tight asymptotic bounds
