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

Day 2 (2022/05/03)

• 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

Day 3 (2022/05/04)

• LeetCode 976
• LeetCode 1779
  • iterators
    • filter
    • map
    • peekable
  • ❓ The performance and memory usage in this implemention is higher than the ones using for loops...why?

Day 4 (2022/05/05)

• LeetCode 1822
• LeetCode 1502
• LeetCode 202
• LeetCode 1790
  • match (somthing similar to switch in C)
  • tuples

Day 5 (2022/05/06)

• 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");
