Learning data structure and algorithms are easy or tough?if it is so how can I learn that

Question

Data structure and algorithms

Answer 1

They are not tough nor easy. But you must practice them almost daily so that you don't forget the concepts. You must apply them to different questions you solve in order to understand it well. You can probably buy a nice book or you can go through the data structure part provided by sololearn. But choose your language of choice wisely for implementation.
