3. Linear time algorithm for selection problem, given n numbers, find the k'th largest in linear time: Typical implementation starts with partitioning the n numbers into [n/5] groups and each group contains 5 numbers or less (the last group). My question is, how about we partition the numbers into 3 in a group or 7 in a group? Please explain.
