Learning Log

Day 1 (2022/05/02)

following LeetCode's Programming Skills I to familiarize myself with Rust
- did questions 1492 and 1523
first time to use Rust! I've learnt about:
- basic data types (integers were mostly used in today's questions)
  - it is cool that there's arch to determine the integer size according to the machine's architecture
- variables and constants: let, mut, const
- if-else statements
- while loop

LeetCode 1491
- learnt about Vector
- revised about pointers
LeetCode 191
- Rust has a method count_ones() in u32 which makes the solution a one-liner lol
LeetCode 1281
- should've used iterator

LeetCode 589 (does not support Rust, switching to Python)
LeetCode 496
- 💩 referencing and dereferencing
- HashMap
LeetCode 1232
- 💩 division by zero
- destructing assignment e.g. let (mux a, mux b) = ("foo", "boo");
