Answers to LeetCode questions in Swift 3

Started primarily for a few reasons:

• First and foremost, Swift is really cool and fun to use! (update: a few files in, beginning to second guess this...)
• I felt like I was becoming too complacent with Python for interviews, work, projects, etc.
• It's helpful to have a central repository for studying when the time comes.
• Similarly, Python provides shortcuts that might hurt algorithmic thought processes that, if existing in Swift, I have not been exposed to.
• Swift is new to LeetCode (as of early/mid 2017), so even if I want to cheat and look at submissions, usually all I can get is the ideas and not the source code.

Hope to keep this as a running repository as I continue to work on algorithms, feel free to PR with your own solutions if you'd like!

Currently included:

• 1. Two Sum
• 2. Add Two Numbers
• 3. Longest Substring Without Repeating Characters*
• 4. Median of Two Sorted Arrays
• 206. Reverse Linked List
• 617. Merge Two Binary Trees

* This one feels especially dirty with the need to encode Strings as Arrays of UTF-8 bits to iterate efficiently. If anyone has ideas for handling this better, please PR it! Stack Overflow and the LeetCode forums can only help so much 😉
