Subject: Math, Cycle Detection
Time committed: 3
Problems tackled: Happy Number, Reverse Integer, Bulb Switcher, Palindrome Number
General comments:
- I’m feeling good about this. One more day (tomorrow) until my first legit interview of the fall season. I’m stoked. I feel more prepared than ever, and I’ll be ready to give it my all. I’m glad I got the chance to review a lot of concepts that I was rusty on, and I’m glad I was able to reinforce a lot of the things that I thought I knew (but then I really didn’t…).
- Tomorrow is the day before the interview, so I think I may focus on less Algo-y stuff and more on general interviewing things (behavioral, web, servers, etc.). After the JS interview, I’ll reflect on how my preparation has gone so far and then recoup for the next stage (the TS onsite!).
Read for next time:
- Floyd’s Cycle Detection Algorithm (really read up on this, brush up on linked lists as well)
- Solution for Happy Number
- Abstract class vs Interface
- Inheritance vs Polymorphism
- OOP!
- Topological sort!
