HW4: late strtok tutorial submission

In the issue I posted , #694, I stated that I was having trouble merging commits. I wasn't able to solve the problem but was able to come up with a different solution. I deleted my forked ucr-cs100 repository, re-forked it, added you and Taeyoung as collaborators again and uploaded the second draft to this new repository. I know that I am past my deadline, but may you please look at what I have?
