I also want to see how you guys solve these problems. People on youtube videos already know the answer. They just told you how to solve it. But I can't see how

I also want to see how you guys solve these problems. People on youtube videos already know the answer. They just told you how to solve it. But I can't see how they approach to get the answer. I think that part is the most interesting and valuable part for non-talent like me.

I ran into this too when I was preparing for a loop, especially for more complicated DP and recursion problems. I found a website called gorecursion [0] on Reddit and he is very good at describing these solutions from the naive case to the optimized case very well. This helped me quite a bit, but I still didn't get the offer. [0]: http://www.gorecursion.com/ http://www.gorecursion.com/

In my experience, you can't learn that skill by watching others. It is a practice, like playing chess, or writing Math proofs. So IMHO the only way is to train. Start with simple problems, and continue from there. Bang your head against problems for a few hours before looking up the solution. Over time, you will get better. Disclaimer: I'm myself not very good at algorithmic puzzles. For a job application I took a vacation to train solving coding tasks, and was getting better every day. I got that job, but guess that for a Google application I'd rather have to train for 3 months.
