Difference between HackerRank, LeetCode, topcoder and Codeforces

[@himanshuranjan5575]

Sound quality can be better. A bit more loud maybe.

[@code_report]

Yep, i've gotten a few requests similar and increased the audio in more recent videos. I also got a pop filter since then :)

[@thakararkeval4759]

@@code_report thanks

[@Wishmeluck99]

Use 🎧

[@klon22]

less boring too?

[@anonamemous6865]

Yeah

[@kernyan-5283]

that's very useful for someone who is interested but has completely no idea where to start!

[@ver_nick]

A lot has changed over the years, and CF has gotten itself a small code editor and it also has a giant forum for discussions.

[@AnthonyMcqueen1987]

You missed so many other sites but yeah i know you cant do them all. But showing the top contenders makes sense. In my experience Codeforces is the most raw in terms of competitive programming. - Very little help - Pure problem solving - Best coders in the world compete in - Most frequent contest

[@code_report]

I plan to make an updated version included the ones I missed.

[@VishalRaoOnYouTube]

@@code_report Looking forward to an update video that includes CodeChef, HackerEarth, and Codewars.

[@jvsnyc]

Excellent breakdown of these four! Glad you solved your sound issues later.

[@thallium54]

I would also suggest atcoder for beginner. It hosts beginner's contest very often which has super easy problems for beginners to start.

[@r_m5545]

You are the best SIR , I hope this channel will grow soon !

[@TheNeyoh]

Codeforces is the best

[@LucTaylor]

I think Topcoder is kinda expecting people to code in the applet.. I find the web interface completely unusable, which they get away with by permanently calling it "beta". The applet is problematic because you have to do some settings configurations to get the applet to run, dodging Java security

[@saikat93ify]

AtCoder deserves to be there too, in my opinion.

[@asdfghjkl1770]

Thank you so much! I am 15 and I love programming! Now I am preparing for Google's Kickstart and Code Jam competetion..... [ Registered as 'im at least 16 yrs old', but it was false!!]

[@liwaiyip1769]

9:45 Leetcode should be on the right-hand side while Codeforces should be on the left-hand side

[@code_report]

wow, good catch!

[@PProgress]

9:46 You switched the pictures xD

[@rahultech77]

dude! you are the greatest! thanks for making this

[@mohammadyounoch5952]

Please rerecord the video in the louder sound.

[@uniquechannel3086]

Content is informative and good but sir please increase the overall sound of the video. Even my max volume on phone is not clearly audible

[@code_report]

Thanks for the feedback! Many people have mentioned this and I increased the volume several months ago! Cheers

[@pratikvartak6387]

Waiting for how to start with competitive programming, coz everyone tells what to do and not how. for eg , do algorithms and data structures but which ones and how to study them as per need or study all and put them in use , so its a big dilemma sometimes

[@Mac087]

What about codewars? Where we it land?

[@shloch2007]

my best actually

[@siddharthverma242]

Sound quality is very very poor.......

[@LucTaylor]

Partial points sounds like nonsense to me "Well your code is DEFINITELY wrong, but we'll give you some points anyway"

[@kaustavbasu]

I din't have a pc back then in my teens. Now I'm 22 and I can solve medium level problems. Is it too late for competitive programming?!

[@an1ketsharma]

Its never too late bruh.

[@tumul1474]

Never too late broo......even if it's late....it's better late than never

[@chegevarra1036]

Why codewars not in list?

[@dhiraj.govindvira]

where is code chef ?

[@sohangchopra6478]

Volume is very low. difficult to hear even with earphone.

[@akshatdhiman8819]

Which platform is best for getting into Indian companies?

[@siddharthmohanty4922]

What about Codechef?

[@animenerd_]

Codechef and HackerEarth are more popular in India but less recognized around the world...

[@animenerd_]

But sites like Codeforces and Topcoder are recognized everywhere in the world.. Its better to have a nicer Codeforces and Topcoder profile than Codechef

[@bin4889]

quality content. great work

[@pragueexpat5106]

There are many such websites out there, too many, are you sure these 4 are the best?

[@midhileshmomidi2434]

Codechef is a combination of all these I think Codeforces is toughest of all

[@RiteshNEVERUNIFORM]

Cant understand anything Full Quiet Video with No sound

[@abhinavgarg630]

I am a college graduate, how can i take part in competitive coding competitions, since my interest in the field grew after the college.

[@aniketshukla540]

Same here

[@aniketshukla540]

Did u find anything?

[@abhinavgarg630]

Spend as much time as you can on codechef

[@bihariyokibaat]

hey,upload a thread of good problems on Dynamic programming,Greedy ,graph theory etc(Basically the important algorithms).you are doing good job.

[@marchanselthomas]

Hey code_report, how can beginner start solving these challenges? Are there any tutorials or books? or any prerequisites?

[@code_report]

I am going to start a series called "How to start with competitive programming" and also another video on CP resources. If you are new though, I would definitely start with HackerRank. Work on the Algorithm practice problems (www.hackerrank.com/domains/algorithms/) and the Data Structure practice problems (www.hackerrank.com/domains/data-structures/) with your language of choice (C++ is my recommendation). While you do this, start entering the HackerRank contests and always make sure the read the Editorials for all the problems you can't solve!

[@marchanselthomas]

code_report will you be teaching in c++?

[@snk-js]

codewars?

[@andrewdwillis6]

cant hear

[@sohamkulkarni5299]

sound quality is too good can you tell me your mic details?

[@code_report]

Just a Blue Yeti

[@deepakprajapati5064]

one like for your work

[@blasttrash]

What if I am not in univ or high school, which contest is close to ioi or icpc for adults so to speak? Google code jam?

[@code_report]

I would say Topcoder Open (TCO), Google Code Jam (GCJ) and Facebook HackerCup.

[@vidhansharma1787]

Codechef......?

[@abhijeet-anand]

bro you sayin something?

[@crazydrifter13]

hahaha....relative content loudness -21db

[@WaffleWithSoda]

Great content!

[@code_report]

Thanks!

[@JoeWong81]

leetcode is the most popular, however Hackerrank was created by Gayle Lawkmann

[@code_report]

it's Gayle LaAkmann, and she did not create HackerRank. Hacker was a Y Combinator-backed company founded by Vivek Ravisankar and Hari Karunanidhi. Gayle is the author of CtCI (Cracking the Code Interview) and she founded www.careercup.com/

[@JoeWong81]

ok sorry bro. But she is associated with hackerrank and she probably has a say in the practise problems as well as company partnership problems.

[@akarshrastogi5145]

No bro, she just has a series of problems on HR that are the set of questions that promote her youtube series on CTCI that in tun promote her book.

[@ariefkurniawan1269]

Topcoder yeaah...🤩

[@dharmamsavani340]

at 9:47 you exchanged titles of codeforces and leetcode because image doesn't match titles

[@35sherminator]

Great video :-)

[@kalidinditejasree5132]

which is the best one???

[@code_report]

Depends on what your goal is. IMO, Interview prep = LeetCode, competitive coding = Codeforces.

[@mortenbrodersen8664]

Really bad sound quality.

[@rahulkumarpatra4206]

Good job

[@ashwiniverma1147]

Listen yourself...., :(

[@kaustubhkislay3126]

sound quality is pathetic....I could barely hear anything even after using earphones.

[@code_report]

Sry, it was one of my earlier videos and i didnt have a good mic or pop filter. And i have increased the dB in recent videos.

[@kaustubhkislay3126]

A good content with a bad sound quality ruins everything. Period.

[@CyberRazeR]

this is stupid distinguishing people on the basic of few thousand of selected code which are already solved this stupid i bet if i give these company a brand new problem they'll need a a day to solve it alone maybe more then one day

[@netbotcl586]

you can start writing contests to verify that. all of them write new contests and problems every few weeks.

[@CyberRazeR]

@@netbotcl586 and why would I do that when I am saying the at most opposite. Tell me does a compitive programmer knows how to apply pimpl ?

[@netbotcl586]

@@CyberRazeR 1. You claimed that you can create a new problem, then do it to prove your claim. 2. You realize there are millions of competitive programmers, right? Many of them have actual jobs in the industry, and know those tricks. Is that question even relevant to your claim?
