What should we do to learn data structure ?

Question

Developing my skills

Answer 1

Watch online youtube videos, if you are not comfortable with videos then buy a book. Start with arrays and learn it well by doing all types of matrix operations and then slowly move on to stack and queue.
Once the above is done start solving problems and take some time before jumping on to other data structures.

Answer 2

There is also a tutorial on SL for that.
