Top 5 Hardest LeetCode Questions I've Solved

[@aminefourati1258]

The solution for the find duplicate number blew my mind away honestly, but I feel like the question was formulated from the answer itself and the specific constraints that need to exist for the solution the work

[@yang5843]

If i ever see a hard Leetcode question in an interview, I'll walk out

[@sanskartiwari2496]

Out of my last 4 interviews, 3 asked hard questions. The avg level is rising and more students are getting competent, atleast here in India. The questions I was asked are by the following names on leetcode Edit Distance : dp, Burst Balloons : dp MCM, Maximum Path Sum : Binary Trees

[@sakilnathaniya423]

@sanskartiwari2496 was the interview for a jr dev or senior dev?

​@@sanskartiwari2496 If you're in India, I feel sorry for you. The stats for the people studying programming that are actually fit for the job are very demotivating. It's become too hard to get a job in programming for the average Prakash. Cheating during an interview is also never ever ever an option.

Burst balloons is a classic crackhead problem.

[@arihantbedagkar7678]

It's an MCM pattern question in DP. If you solve MCM type questions, bust balloons is not that hard.

[@mohitkanodia5388]

What is mcm pattern?

[@XYZ-ow8lx]

It is a combination of DP and div & conq ... it is a classic problem of its type probably you didnt come across this problem b4 that is why you felt hard

[@stage666]

​@@XYZ-ow8lxthey are all FK ING useless aside from passing the interview and getting into the rat race.

When I first studied KMP algo , I didn't understand it in first go. I had to watch it twice.

[@mohabkhaled1391]

to further on KMP, where does the textbook and academic algorithms stand in this world - leetcode, interviews ..etc.

[@CreamusG]

If you need to know a bunch of academic algorithms for your job, you probably are long past the interview process lol

[@GouravMoondra]

the only one i have come across from this video is kmp algorithm , i have watched so many explanations and i still dont understand why it works so i just memorized the code which is not that difficult .

Approach 5 in the editorial of Knight Dialer is pretty insane too.

[@電腦騙徒剋星]

modelling dp as matrix problem is pretty standard in competitive programming

[@zzzzzzzjsjyue2175]

knight dialer is not very hard tbh

Hi, first, my hardest so far sudoku validator, pretty basic problem, but I am only solved 30 of them.

[@samarthjain5015]

That was the first medium problem that I solved.

[@mct6902]

There was a meta question asking if a mouse can escape the room while a cat is catching. Both were at the same speed. The room has obstacles, and if the mouse can reach any 0 near the edge of the matrix before the cat can reach the mouse anytime before or at the same time, it means the mouse can escape. The follow-up was if there are "steroids" in the matrix if either the mouse or cat eats it will double its speed, can the mouse escape?

[@alek4001]

Sounds like complex simulation problem. "864. Shortest Path to Get All Keys" is somewhat similar. I do not think it has "clever" solution or specific "named" algorithm.

[@samarthjain5015]

Make an "Easiest Leetcode Hard problems". It's time for me to increase the number of hard problems solved.

[@butoyighyslain171]

word!

[@ssuriset]

Okay, find the duplicate number is one of those where you can’t do it on an interview if you haven’t seen it before.. like the tortoise and hare.. the Regex question was asked in my friend’s Amazon OA apparently and I wanted too solve it, and I still can’t.

[@MBXD001]

Bro have you cracked the book introduction to algorithms ? by cormen

[@greatestever2914]

i got stickers to spell words on my meta phone screen :')

[@adityarao4157]

i think it might be verbal arithematic puzzle, literally i skipped it , (i have never skipped a problem atleast i understand then implement by resources but never skipped) it hits me different, but now i ll solve it after seeing this video

[@ihsannuruliman4005]

Burst Balloons and New 21 Game. I'm skipping those two because they're just out of my mind.

I have a question whether it is possible to enter Faang without a degree (any degree) or not at all.

[@ianokay]

100%

[@zzzzzzzjsjyue2175]

it technically is but most likely not worth trying because more likely than not you will fail. Most faang engineers are top students from top universities so that is your competition

[@Ruby_Ai]

@@zzzzzzzjsjyue2175 thanks for answer, but I am going to try anyway, it's not like I need to drop from my job to interview there)
