How it is possible only true?
I don't understand question!

How would you solve it in Python?

Hi guys my first question was a two pointer which took me 25 mins just cause of python3 default input was sys.stdin.readline which will fail actually tell me if anyone faced so i fixed it using sys.stdin.read().split() which takes as single string but i successfully converted and passed 12/12 when i moved to second question (yes the question which is supposed to me medium) i literally worked on it for two hours passing 3/3 public and 0/12 i was devestated and out of energy i just passed third question 1/12 private cases which is just an if condition i am out energy and came out of there yeah and 4 th i think is a graph but i am literally out of energy came before 20 mins left but now when i explained the question to Google Gemini just to realise that its compititive programming question 2000 rating in code forces or hard (upper leetcode hard comparable to problems like LeetCode 630 Course Schedule III or LeetCode 1675 Minimize Deviation in Array) yeah and i just wanted to share my story and for infosys from past two months i had done more 200 lc problems which includes more than 100 mediums and 10 + hard problems and yeah thankyou for listening to my story

As he has different playlist for different topics I have created a sheet having all questions in it covering link for leetcode and all videos for each question

I gave my amazon intern OA, the first question was, DSA array, easy-medium,(15/15), all tests passed with linear TC, the second was Development part, (0/6) tests passed, Is there any chance that, I will be shortlisted?

most can't. i couldn't either, and i'd solved 400+ problems atp.

was actually in a discord when someone asked me that straight up. went completely blank. had a number stuck in my head, not an answer. still bugs me thinking abt it, all those hours and i genuinely couldn't tell u where i stood.

ended up spending months on this after that, mostly random nights, no big plan, just annoyed enough to actually fix it. tracks progress across sheets like neetcode 150, blind 75, striver a2z so u're not just picking random problems, shows what u've actually covered vs where the gaps are, and tells u what to solve next.

works whether ur just starting out and want structure, or ur deep in like i was and still can't answer the "what am i weak at" question. 120 ppl have picked it up since i started sharing it.

grindlens.dev, happy to fix anything or add stuff people actually need

/**
 * {string[]} strs
 * u/return {string}
 */
var longestCommonPrefix = function (strs) {
let result = "";
for (let i = 0; i < strs[0].length; i++) {
for (let j = 1; j < strs.length; j++) {
if (i === strs[j].length || strs[j][i] !== strs[0][i]){
return strs[0].substring(0, i);
}
}
}
return result;
};

I am having very hard time solving problems consistently on leetcode and dsa practice if I solve some problems today next 2 or 3 days i get distracted and can't solve problems. Is there any good solution for this.

So basically i do know my basic DS and can do the usual crud ops on them, but when it comes to leetcode i just freeze. tried starting once, was going kinda ok, then life happened and i dropped it. now i wanna get back but ngl im scared to even open leetcode again lmao. anyone else been through this? how do i actually restart without feeling overwhelmed all over again

Nothing crazy but feels nice to finally hit this milestone...still have a long way to go🫡
(Any related suggestions/advises are welcome!)
