I struggled with git until I learned these 17 commands: 1 git add ↳ It lets you add changes from the working directory into the staging area. 2 git commit ↳ It lets you save a snapshot of currently staged changes in the local repository, with a message.

Give me 2 mins and I'll teach you how Big O works: • Big O tells how much slower a code gets as the input increases. • There are best, average, and worst cases for a specific algorithm. • Also there are Big Os for time, memory, and storage efficiency.
