(Solved) : Given Set N Numbers Wish Find K Smallest Numbers Sorted Order Using Comparison Based Algor Q31537320 . . . .

 

Given a set of n numbers, we wish to find the k smallest numbers in sorted order using a comparison based algorithm. Below are some possible algo- rithms for this problem. For each algorithm, analyze its running times in terms of n and k. Note that all algorithms must be comparison-based. We assume that all numbers are distinct. 1. Sort all n numbers, and output the k smallest numbers in sorted order 3. Build a heap on the n numbers by repeatedly inserting them into an 4. Can you design an algorithm better than all three above? Hint: use 2. Build a heap on the n numbers, and call Extract-Min k times. initially empty heap, and call Extract-Min k times. the deterministic linear-time selection algorithm.]
