Wow, I'm so happy(: (: Today I tried leetcode for the first time, solving my first problem.
I didn't know how powerful learning by doing is until I actually experience it here in leetcode!!
The process of trying to solve a problem on your own, get stuck, try to think and analyse your code in order to spot errors or unefficiency, and then see how others handle it, makes the learning material memorable!!
Now I believe if I want to read any book on data structures and algorithms, its gonna be much more relative, meaningful, and therefore much easier, as they explain in depth stuff I already know, or have an idea about.
I think that aligning the right learning approach with the very subject you want to learn, is a significant requirement skill to thrive in the rapid-learning era we live in, as technology changes rapidly.
I discovered that learning by doing is far far better than any learning approach !!! Not strange why cognitive scientists emphasize it so hardly. Thank you too much (haha) leetcode
