Complete the program we saw in class number 13, which can be found here: http://rabbit.eng.miami.edu/class/een421/dios-assign.txt There are four places where it says /* YOU IMPLEMENT THIS */, you should do what it says, and implement those missing functions. One is very easy, one is quite tricky, the others are somewhere in between. Whe you are finished, all of the test options at the end should work properly. Take care to use freevec in the right places, we don't want any memory leaks.
