An algorithm for computing the kth smallest number in a given list of n numbers is in time O(n). The algorithm worked by breaking the numbers into n/5 sets of size 5, and the then considering the medians of these sets. We set w to be the median of these medians, and used it to split all the numbers and recurse. What bound would you obtain if you analyzed the algorithm that uses sets of size 4 in the above process? (The median of 4 numbers a1 a2 a3 a4 is a2+a3 2 ).
