I need help adding a delete function to the following skip list code. I also included what the output should look like. I Write a function that takes the test size as parameter and then based on that your code will randomly generate two set of test size number of integers within the range of $0$ to $2000000.$ The first set of numbers will be used for insertion and the second set of numbers will be used for deletion. Before the insertion process, start the timer using $$System$.$currentTimeMillis$()$;$$ Then insert all the items to your skip list $.$Then delete the list of items you have generated from the skip list. Stop the timer and calculate the time taken. Do$,$ the same thing for Treeset. In the main function, declare this array and pass each of them to the test functions.
