Hope you all completed this 😊😊

Either wrong or right please let me know will help you in

If you will solve this i will refer your profile in Amazon for SDE1

When I started learning 𝗗𝗦𝗔. I didnt know how difficult it was going to be or for how long I will be able to give time to this. I only knew basics of C++ and some basic data structure like: stacks and queues.

And still, DSA and System Design are the two things upon which you'll be most grilled on in interviews of almost all product-based companies.

But bhaiya, mai try toh kar rha hu, par questions hote hi nhi hai.

Kya karu, I'm getting demotivated.😐

I remember, I also feel the same way when I started with DSA in my college.

I heard about 𝗦𝗣𝗢𝗝, 𝗰𝗼𝗱𝗲𝗰𝗵𝗲𝗳 and 𝗵𝗮𝗰𝗸𝗲𝗿𝗿𝗮𝗻𝗸 in college. I tried 𝗖𝗼𝗱𝗲𝗖𝗵𝗲𝗳, could not understand the UI and how to read the inputs in my program, so I left it. Looked at 𝗦𝗣𝗢𝗝, didnt like the UI either.

I tried 𝗚𝗲𝗲𝗸𝘀𝗳𝗼𝗿𝗴𝗲𝗲𝗸, then jumped to 𝗖𝗼𝗱𝗲𝗖𝗵𝗲𝗳, 𝗛𝗮𝗰𝗸𝗲𝗿𝗘𝗮𝗿𝘁𝗵, 𝗟𝗲𝗲𝘁𝗖𝗼𝗱𝗲, etc, and in fact participated in a lot of contests.⭐

It's not really hard to master DSA. It's just you need to be more consistent in solving at least a problem daily.

Believe me, Consistency is the Key ⏳

Some of the Major reasons people not improving in problem-solving and DSA is they are lacking consistency.

Hard to do LeetCode or GeeksForGeeks daily, but if you convince your mind to do it as a habit then it will be easy.

No matter what happens, you will 𝗳𝗲𝗲𝗱 𝗼𝘂𝗿𝘀𝗲𝗹𝘃𝗲𝘀 daily because you have been doing it for a long time and you have no trouble doing it.

Try to do same habit with your favourite coding platform..

Fix a slot in the day / night as per your convenience, and do LeetCode daily at the same time.

Doing this 2-3 months without missing a single day, missing a day will be more difficult in doing LeetCode that day.

You'll soon see the magic of being consistent in your problem-solving skills.

Freshly, I came across this useful resource of DSA. You can have a look at it by clicking on the given link below.

I will share the link for learning only when you will complete above code 😊😊
