Day 69

The specially numbered day.

I completed 3 questions today. First is a leetcode easy. Somehow how my space complexity increased when I removed commented code. That makes no sense. https://leetcode.com/problems/number-of-recent-calls/.

Second is a leetcode medium. https://leetcode.com/problems/single-element-in-a-sorted-array/. The question basically tells you to use binary search. Figuring out the concept wasn't too bad. I hate dealing with the edge cases on binary search. I'll need to remember to have the while loop condition be left <= right, and not left < right, just to make things easier for me.

Third is another leetcode medium. This was similar to some question I answered before. I don't remember what that question was, but the same concept/pattern applied. https://leetcode.com/problems/number-of-smooth-descent-periods-of-a-stock/.

12 more to go.
