> TWO PROBLEMS in 1 day One of the dirty little secrets of studying CS and math is that truly understanding 2 problems of the kind you've never seen before in 1 day is OK and expected. Hell, sometimes mere understanding of one single solution to a problem can take a week or longer. Most anyone who does better has either studied the (adjacent) material before or just trudging along half-understanding this bit and that…
I'm certainly lacking in the experience boat. But, I've figured the "way of thinking" is likely that I am not thinking in an algorithmic / math fashion. I don't "see" the solutions in the same way that someone with a mind for math would. Instead I just see the brute force, "obvious" solution.
I'll definitely take a look at these resources.
