## Data Structures and Algorithms Problems

I personally found reading this very helpful. Read the problem, come up with a solution, compare your solution, read on to see if there is an optimization, think about the optimization, implement it, then go back and read about their optimized solution. Some problems have stages of optimization which I found were good to read and simulates an interview better — building in small steps and increasingly getting harder.

My goal will be to use this to both practice my skills, and learn new languages. Thanks for compiling the list! Thank you for this! This will help me prep, get better at programming and feel more confident overall.

Thank you so much this. This is truly an amazing site; something that I will use quite frequently in the months to come with my studies. I just wanted to leave a message of thanking you for such a great material.

I want to prepare for technical interviews and I find your website to be very helpful especially the solutions provided with the problems are really good.

This is super interesting list of questions and the best possible solutions discussed in terms of time and space efficiency from brute force solution to the most optimum.

I looked at the first problem: finding pairs in a set whose. I was surprised how thorough it is described, with a naive solution, a better solution using sorting, a better solution still using hashing, a finally a link to a page describing finding such pairs in a binary tree. I wanted to thank the author s of the DP articles! They have been one of the best resources I have found online.

Keep up the great work! I have been using your website for quite a while and I find it to be absolutely great in DS and Algo preparation for technical interviews. The explanation and the solution TechieDelight provides on most questions is probably the best available online, much better than every other website.

Thank you and your team for helping me in my preparation. Your collection is just amazing. The way you have explained your stuff is fabulous. Naive method. Then Optimized methods. At times I feel that you are in my head. Great work. Keep it up. Thanks a lot. You need to promote more. This website is a gem. Thank you a lot. TechieDelight helped me land in my current job.

I really appreciate the effort you have put in creating this site. I flunked out of a half dozen first round technical interviews. Amazon, Microsoft, Google, a few startups, Facebook, etc. My mind would always blank out when it came to solving problems. It happens to everyone. As someone who recently finished a data structures class, I wish I knew about this site before today!

Thanks for this wonderful website. May god bless you. Big thanks for the amazing tutorial!! This is truly going to be invaluable, thank you! What a site I came across; Thank you so so very much for this. Very well organized and really helpful. I think this site would help tremendously in CP and also for those geeks , in search of beautiful optimizing algorithms!!!

The test lasts 90 minutes, using a laptop with an IDE. Maybe a better approach would be both interviewer and interviewee are given a problem from an independent third party. Holy crap, this Looks awesome!!! Skip to content. Primary Primary. Like us?

Oleg Abrazhaev. Juan Gonzalez. This is surprisingly nice list. All problems I have encountered so far were very challenging.. Tanmay Jha. Thank you for the solutions. The optimization part is being really helpful. Bookmarked this for when I actually know algorithms and data structures. Praveen Marri. I tried several sites before, this is the best resource found till date.

Wonderful web site. I am sending it to a few buddies. Thanks to your sweat! Akash Krishnan. Daniel Ro. Awesome set of questions! Thank you so much for compiling these! Can you sort the problem according to the difficulty level it would be good for beginners.

Kaushal Agrawal. Hi TechieDelight! I would like to thank and appreciate the wonderful effort! Load More Comments.

О Боже. Значит, она слышала звук выстрела Хейла, а не коммандера. Как в тумане она приблизилась к бездыханному телу. Очевидно, Хейл сумел высвободиться. Провода от принтера лежали .

Кардинальное отличие Монокля заключалось не в его миниатюрном дисплее, а в системе ввода информации. Пользователь вводил информацию с помощью крошечных контактов, закрепленных на пальцах. Контакты соединялись в определенной последовательности, которую компьютер затем расшифровывал и переводил на нормальный английский. Киллер щелкнул миниатюрным тумблером, и очки превратились в дисплей.

Даже его безукоризненный лотос беспомощен перед эскадрильей вертолетов Агентства национальной безопасности. Сьюзан - это единственное, что не позволит Стратмору меня уничтожить. - Сьюзан, - сказал он, волоча ее к лестнице, - уходи со. Клянусь, что я тебя пальцем не трону.

Ступени были настолько крутыми, что на них нашли свою смерть множество туристов. Это вам не Америка - никаких предупреждающих знаков, никаких поручней, никаких табличек с надписями, что страховые компании претензий не принимают. Это Испания.

Расплавленные остатки миллионов кремниевых чипов извергались из ТРАНСТЕКСТА подобно вулканической лаве, густой едкий дым поднимался кверху. Она узнала этот запах, запах плавящегося кремния, запах смертельного яда. Отступив в кабинет Стратмора, Сьюзан почувствовала, что начинает терять сознание.

Да. Такое впечатление, что он его буквально всучил - канадцу показалось, будто бы он просил, чтобы кольцо взяли. Похоже, этот канадец рассмотрел его довольно внимательно.  - Стратмор остановился и повернулся к Сьюзан.  - Он сказал, что на кольце были выгравированы какие-то буквы.

Внезапно он взвился в воздух и боком полетел вниз, прямо над Беккером, распростертым на животе с вытянутыми вперед руками, продолжавшими сжимать подсвечник, об который споткнулся Халохот. Халохот ударился сначала о внешнюю стену и только затем о ступени, после чего, кувыркаясь, полетел головой. Пистолет выпал из его рук и звонко ударился о камень. Халохот пролетел пять полных витков спирали и замер.
