The program tests different array sizes to establish a relationship between input size and runtime. It tests each array size multiple times and then takes an average of the times. We also output how much the average runtime increased relative to the previous average. This is calculated by dividing the current average by the previous average (output "N/A" for the first increase value). Here are example calls to the timing functions: functionRuntimes fRT; int sizes1[] = { 2000, 4000, 8000, 16000, 32000, 64000, 128000, 256000}; srand(time(0)); fRT = timeAlgorithm ("Insertion Sort", 6, 5, sizesi, insertionSortInitial ); printRuntimeTable(fRT); freeFunctionRuntimes (fRT); fRT = timeAlgorithm ("quicksort", 12, 8, sizes1, quickSortOptInitial ); printRuntime Table (fRT); freeFunctionRuntimes (fRT); This results in following table: Test #2 0.008 0.030 0.119 0.471 1.902 Test 13 0.007 0.038 0.119 0.476 1.926 Test 4 0.008 0.030 0.119 Test 4 0.008 0.030 0.120 0.475 1.917 Test 6 0.008 0.030 0.129 0.476 1.981 Average 0.008 0.030 0.119 0.476 1.924 Increase N/A 3.950 3.939 3.985 4,043 1.895 1.922 Insertion Sort Test size Test 1 2000 8.008 4000 8.031 3000 8.120 16000 0.484 32000 quicksort Test size Test el 2000 0.000 2000 0.002 16000 32000 0.004 0.008 64000 0.017 128000 0.035 256000 0.076 Test 48 Test #11 0.000 Test #7 0.000 0.001 4000 Test 26 0.000 0.001 0.002 0.001 Test #12 0.000 0.002 Test #S 0.000 0.001 0.002 0.004 0.000 0.001 0.002 Test #2 0.000 0.001 0.002 0.008 0.016 0.034 0.071 0.666 Test #3 0.000 0.001 0.002 0.004 0.000 0.017 0.034 0.071 Test 4 0.000 0.001 0.002 0.008 0.016 0.035 0.071 0.004 0.002 0.004 Test 29 0.000 0.001 0.002 0.004 0.008 0.016 0.034 0.072 0.004 0.008 Test 10 0.000 0.001 0.002 0.004 0.008 0.016 0.034 0.071 0.002 0.004 0.001 0.002 0.004 0.008 0.016 0.034 0.071 2.124 Average 0.000 0.001 0.002 0.004 0.008 0.016 0.034 0.071 0.008 Increase N/A 2.027 2.055 2.071 2.100 2.036 2.076 0.016 0.034 0.071 0.004 0.006 0.016 0.034 0.071 0.008 0.016 0.034 0.071 0.018 0.035 0.070 0.008 0.016 0.034 0.071 Note your runtimes will vary a bit since the test data is randomly generated. The runtimes are stored in a functionRuntimes struct. You are completing a program to create and fill data in this struct, print the data of this struct, and free this struct. You are given a partial implementation in the file "runtime Table.c. Specifi- cally you are tasked to complete the functions below the heading "Functions for finding and printing runtime. No other functions should be changed. Using the Program (5 points) After you have the program completed, you should use it to help determine the asymptotic runtimes of the three mystery functions (i.e., mysteryRuntimel, mysteryRuntime2, mystery Runtime3). Be sure to also examine the code of the mystery functions to confirm/improve your estimations. Fill in the following table in the provided file: /* TODO: Give your asymptotic estimates for the runtimes of the following 3 functions: mysteryRuntime1: 00) mysteryRuntime: 0 ) mysteryRuntime3:00) */ Deliverables: Your solution should be submitted as "runtime Table.c".
