In this lab we will empirically deduce the runtime performance of given functions. Inside of src/main.cpp you will see 5 functions (problem1, problem2, problem3, problem4, and problem5). For each of the functions:
1. Empirically generate a performance graph (via gnuplot) for each function. These may be separate files or all in one file. Make sure it is obvious which plot is which.
Determine the theoretical Big O of each function. Write ALL Big-O answers in one file
