Implement the following algorithms: 1. Insertion Sort 2. Merge Sort 3. In-place quicksort (any random item or the first or the last item of your input can be pivot). 4. Modified quicksort: a. Use median-of-three as pivot. b. For small subproblem size ( ), you must use insertion sort. Execution instructions: 1. Run these algorithms for different input sizes (e.g. = 500, 1000, 2000, 4000, 5000, 10000, 20000, 30000, 40000 and 50,000). You will randomly generate numbers for your input array.
