Problem 4. The scientists of Space Lab want to sort their remote sensoring data to reconstruct the 3-D images of the surface of Mars. They have one million 64-bit integers to sort 1. If they use quicksort, estimate the number of key value comparisons per formed. (Hint: consider the average time complexity of quicksort.) 2. If they treat these integers as four-digit, radix-210 numbers and use straight radix sort based on the radix-216 notation, how many sorting passes are required to do the sorting? 3. Unfortunately, the computer in the Space Lab has only 9 megabytes of available memory for running the sorting task. Is it practical to choose bucket sort to be the stable sorting method in the implementation of the above straight radix sort! Explain your
