| 2 | +Getting Started with DSA:- |
| 3 | + |
| 4 | +To start with DSA, one can purchase course on any edtech platforms or can buy it from some offline institutes. |
| 5 | + |
| 6 | +But in this article I will be focusing entirely on free resources. |
| 7 | + |
| 8 | +So there are two situations:- |
| 9 | + 1) You don't have any knowledge of any programming language. |
| 10 | + 2) You know basics of any OOPs based language (Java,C++,Python). |
| 11 | + |
| 12 | + 1) If you don't have any prior knowledge of any OOPs based programming language then start to learn from Youtube (preferably C++), there are many playlists out there. |
| 13 | + |
| 14 | + After learning c++, move on to the next situtation. |
| 15 | + |
| 16 | + 2) If you have basic knowledge of C++, then register on HackerRank and start solving problems based on the programming language you have learned. |
| 17 | + |
| 18 | + Now learn basic STL in C++ or anything similar in java/python. |
| 19 | + |
| 20 | + Now make profile on any of the online judge like CodeChef and CodeForces. |
| 21 | + |
| 22 | + Start practising problems sorted in increasing difficulty order. |
| 23 | + |
| 24 | + After practising on these sites for 20-25 days you will feel confident. |
| 25 | + |
| 26 | + Now get started with the Data Structures, Refer to this playlist for DSA in C++, believe me this is the best free resource on the internet. |
| 27 | + |
| 28 | + DSA Playlist: https://www.youtube.com/playlist?list=PLDzeHZWIZsTryvtXdMr6rPh4IDexB5NIA |
| 29 | + |
| 30 | + You can skip the topics which is already taught. |
| 31 | + |
| 32 | +If you are comfortable in learning by reading you can also visit Geek For Geeks, they have all the algos and data structures on their website. |
| 33 | + |
| 34 | +Once you have studied till array, make profile on GFG or LeetCode and start practising out there by sorting the problems in increasing dificulty order. |
| 35 | + |
| 36 | +That's it. |
| 37 | + |
| 38 | +Once you have completed the course, just don't stop practising, DSA is like maths once you stop practising you will loose your grip. |
| 39 | + |
| 40 | +Happy Learning :) |
