You can actually find the median by running a sorting algorithm and stopping early, as soon as you know the median. (a) Assume you use Bubble Sort to find the median of 9 elements (i. e. n = 9), but stop as soon as you know the median. Exactly how many comparisons do you use (in the worst case)? (b) Assume you use Mergesort to find the median of 9 elements (i. e. n = 9), but stop as soon as you know the median. Exactly how many comparisons do you use (in the worst case)?
