how do u remember the codes to do a specific thing which u want to..whenever i try to do it..i cant do it..

Answer 1

For algorithms, concepts, data structures and such: Understand them. Why each letter, why each character exists. I did not memorize how to write stacks and queues, I understood how they work and I let myself figure the rest out either with logic or with the little memory I have of it.

But ofcourse try to remember the best way of implementing it.

For apis and ourside libraries, and its implementation, just practice and repeated use. I always have the documentation up.

Answer 2

Try to analyze or trace the programs.
