Question 2. Implement the InsertionSort and MergeSort in java. Then measure the runtime of each algorithm for integer arrays of sizes given in 2A through 2D. 2.A.) size n 100 case 1: for a sorted array of ascending order, -case 2: for a sorted array of descending order, case 3: for an unsorted (random) array 2.B.) size n-1000 case 1: for a sorted array of ascending order, case 2: for a sorted array of descending order, case 3: for an unsorted (random) array 2.?.) size n-10000 case 1: for a sorted array of ascending order, case 2: for a sorted array of descending order, case 3: for an unsorted (random) array 2.D.) size n 100000 elements case 1: for a sorted array of ascending order, case 2: for a sorted array of descending order, case 3: for an unsorted (random) array Plot the input size vs. runtime graph for each algorithm for each size and for each case. You can plot the graph either manually, or by using an automated tool. Compare and comment on the results. Please attach your program source code to your submission. Hint: For your convenience, you may randomly assign elements to the arrays
