title: create plots of number of comparisons between Merge Sort and Insertion Sort
body: <p>I'm required to create 2 plots of comparing between Merge Sort and Insertion Sort.</p>
  
  <p>n = input or number of elements in the array that will be sorted
  nc = number of comparisons performed by each sorting algorithm.</p>
  
  <p>the first plot shows the results of Merge sort and Insertion Sort using a log × log scale (on the x-axis log(n), on the y-axis log(nc)).</p>
  
  <p>The second plot shows the results of Merge Sort using log(n) x (nc/n) scale (log scale on the x-axis only and the y-axis shows the values of nc/n)</p>
  
  <p>Could someone please explain what the (log(n) x log(nc)) and (log(n) x (nc/n)) scale mean?
  I don't understand why we should use the log to create the plots, and what log(n), log(nc), (nc/n) mean in the plots.</p>
  
  <p>Thank you very much and I really appreciate your help.</p>
