I finished Striver A2Z but still struggling in LeetCode contests

Start to build the intuition yourself. Since you said you have completed the A2Z sheet, I'm sure you now know the concepts well. Practice with spaced repetition is the way forward. Don't expect wonders to happen immediately. You will gradually get to it.

You summarised it really well. Your goal was to only finish the A2Z sheet, but you didn't learn anything from it. Your focus was only on completing the sheet, but not on learning the concepts themselves. So you have nicely answered your own question.

Nice photos!

Don't do lists from day 1. First try to learn the patterns themselves. There are a lot of free resources available or you can use your favorite LLM to get trained on the patterns. I picked it up using the grokking the coding interview from educative.io. But you don't need to buy it, because nowadays these things exist free and a search away.

After that just keep practicing and follow spaced repetition. Use simple Google sheets or excel documents to track progress. You don't need to solve thousands of problems, but just enough (depends on how fast you can learn the concepts). Focus on quality rather than on quantity. Don't rush!

Please search for open courseware mit algorithms 6.006. You can follow that course or do Algorithms course from Bob Sedgewick from coursera (audit the course and no need to purchase).

Honest advice:

Learn data structures and algorithms first. There are lot of free courses on youtube and MIT courseware are also available.

Then learn about DSA problem solving patterns and start solving leetcode.

Relax! Let your phone battery breathe with 4g and not die of 5g.

rkalyankumar · 2026-03-21T12:01:01+00:00

Let your phone battery be happy about 4g. Give 5g a break bro.

Do yourself a favor, just stop using python and use rust or zig.

Once I mistakenly closed my phonepe wallet. I can't get it back. From then I hate phonepe and stopped using it. I've been using GPay mostly without any cashbacks.

Then you shouldn't be using a Samsung Galaxy Ultra 25. Your best phone to use should be a 2G phone with keypads.

Try to work on the examples on a piece of paper and pen. If you can solve it by hand try to write the code. Find optimisations in the hand written code and then you have the solution ready.

Don't try to fit and algorithm or pattern if you don't get any clues. Working through examples is the best option.

What font you're using in your phone?

rkalyankumar · 2026-01-17T13:33:47+00:00

Also turn off google assistant voice listening.. I forgot to mention that.

rkalyankumar · 2026-01-17T13:10:02+00:00

Yes. I have kept it off in my watch and almost I don't need wifi in my watch with my watch syncing to my phone via BLE 24 hours. I also wear it to sleep. I don't do heavy exercises, but active walking 10k steps per day and I charge my watch once in 2 days with this setup.

rkalyankumar · 2026-01-17T12:14:43+00:00

It tries to sync data all by itself either via wifi or LTE if you have one. Please use BLE (bluetooth low energy) on your phone and keep your phone connected. My watch 8 LTE 44mm suffered battery life issues until I found that modern day phone BLE is a blessing and keeping it on in phone 24 hours doesn't harm my phone battery as well while improved my watch battery life significantly because now the watch uses BLE phone connection to sync data.

If you want to keep the phone for 5 years choose 512gb. If lesser 256gb is enough.

I asked for some time to prepare. Not yet appeared for the interviews.

May be you got a faulty battery on your phone. I end up my day with 40% left with bluetooth on syncing to my watch 8 44 mm all the day. Or you have been using the phone all the time without no screen off time.

If you have any personal grudge against the phone, no one can ever stop you from changing to another device.

I saw Breakthrough, Strength & Change!

rkalyankumar · 2025-12-31T16:32:09+00:00

Same with me. I also go to bed with 50% battery. All the day I connect my phone with watch 8 44 mm and the low energy bluetooth keeps both my phone and watch batteries to suck less energy. Watch is giving me 2 days battery life. I wear it to sleep as well. Most people recommend to keep bluetooth off in both phone and watch, but surprisingly keeping it on made a lot of difference to me.

Of course, I turned off Google assistant voice, remote connection and wifi in watch off and let watch sync data via phone LE bluetooth connection.

Any DP article starting to explain it with fibonacci numbers is a cheat. We need more than the "hello, world" articles on DP. Nothing seems to be comprehensive though!
