Finished GUIs (Finally!!!!)

 Hello again guys, 

I've finally finished studying GUIs for Java. I've also studied searching and sorting algorithms which were included in CS102's curriculum: Selection Sort, Merge Sort & Quick Sort. (I studied them last summer in Harvard's CS50x, so I knew about them a bit already), exception handling (try/catch), and a little input/output ( just for the external files). 

There's only Java collections framework, basic data structures, and tree structures left to study from my CS102 course next semester, but I will probably look into input/output more.

I've also finished CS50 AI's third video (week 2) and started the fourth (week 3) one a little (obviously, I couldn't watch a half each day :( ). I've found some solutions for LeetCode questions, but I haven't written them to the website, so I don't know if they're fully working.

I also realized that I didn't study Javascript at all. Maybe I look into them in the upcoming week.

That's all from me for now!
