I&#x27;m 16 and I found out that there were way too much material for CS. And I&#x27;m lazy to filter them out. I tried these &quot;Online CS Courses&quot; but I found them too difficult(e.g. what is union? ). I know and understand the very fundamental elements of CS(e.g. tree, array, hash, bitwise logic, boolean, sorting, etc.), but how the am I going to continue CS without appropriate material?
I wonder if I should buy &#x27;The Art of Computer Programming&#x27;, by Donald Knuth. Was it a good book for me?
Reliable resource for intermediate CS?
