1: easy peasy
1.5: thought about it a little bit
2: getting harder
2.5: maybe not that easy
3: alternative solution required
3.5: this makes me f*cking exhausted
4: not solved / solved after watching solution
- After getting the first part correct. Take Day 3 for example, if you got first part correct (i.e. you parsed the input correctly), the second part is not that hard
- Debugging this one is just pain because the "edge case" is not included in example input
- If you know some math, else it will be 3 for one of two parts today
- Reasons below:
- There are too many special cases that I can't know from any way
- I have no idea why my latest algorithm, compared to other methods, is the only working algorithm
- There's no way to know where my code went wrong: 1000 inputs, weird output formula that doesn't even take calculation results as parameter
