Answer 3

First build your data structures from scratch.
You should have clear fundamentals of linked list, stacks, trees and hashmap.
Then practice questions as much as possible.
Now go for algorithms and if any problem occurs then sololearn or other forums is your guide :)
Practice from any competitive online platform such as HackerRank, HackerEarth or codechef.(I would suggest HackerRank if you are a beginner)
