Hello,
I am struggling to find a good way to learn from these problems. Currently I am only able to solve about 50% of the easy problems with a brute force approach. In terms of medium problems the percentage drops to around 15-20%. I make an honest effort with these problems but after spending a couple of hours with little progress I look up the answer. I understand the answer but feel like I am not learning anything from it and have trouble recalling it when I redo the problem. I understand that memorization is bad. How do I effectively learn approaches to solve these problems that I get stuck on and have to look at the answer? Any input would be helpful. I am a young developer trying to get better.
