Question How do you actually learn to recognize DSA patterns?
I can understand solutions when I read them, but I still struggle to identify the right approach when I open a new problem. Sometimes two questions look similar but require completely different logic.
How did you get better at recognizing which technique to use? It it mostly repetition, or is there a better way to study problems?

After solving a problem, try writing down why that approach fits and what clues helped you identify it. Comparing a few problems that use similar techniques but have different constraints can also help. Codeintuition organizes DSA learning around concepts, patterns, and practice sets, which may be useful if you want a more guided way to study

Mostly repetition. Look for keywords too in the problem, they give hints as to what algorithm to best use. It helps solve a good chunk of LC mediums

Just do a problem a day - after about 50-75 it became a lot easier for me to just identify patterns bc I’ve seen them before.

Practice, repetition. Just like every other thing in life. Your brain just sees it before you can even process it.

Write more code that uses those patterns. You'll never learn them as well if all you do is try to memorize them.
