#8 Session 7: Hash Maps / Increase your coding speed

Notes from Facebook’s ABCS Programme.

Remember, aim to solve 2 problems in a 45 minute interview

If you’re not at your most comfortable pace yet, that’s okay. There are multiple ways to increase your coding speed.

How to increase your coding speed

Practice:

• Deepen your understanding of your programming language
• Write more code
• The more practice you get, the faster you’ll get with implementation, getting your code right, or avoiding trivial / or non-trivial bugs
• After solving the problem once, try solving it a different way

Try to write code with fewer lines

• Find the source code to projects and frameworks you already use, and read the source to see how it was written and the choices made
• Figure out what is minimum viable code and try solving problems with the least amount of code possible.
• Challenge yourself to solve the problem again in 50% fewer lines of code.
• Think first, code second.
• Practice while tracking your time.
