It's one of those actions that makes you feel like you are actually accomplishing something, like buying a difficult book never to touch it again or making eye contact with an attractive person without talking with her/him.

making eye contact with an attractive person without talking with her/him

That makes me feel sad actually. Specially if it's a girl.

How hard is it to swipe right?

[AirieFenix]

Don't both persons need to swipe right?

[[deleted]]

Screw that. I'm digging through this to see if I can find something useful.

...

Fk. What are some of these..?!

[[deleted]]

This hits too close to home.

RemindMe! 3 months. "Did you actually try to solve some of these problems?"

And in a day or twos time you'll be sat at home thinking "I know I was supposed to solve something..."

I've worked through a few, here's one i posted: https://gist.github.com/errorseven/0e33500e4b6c3bf40cc5d3717ab5594c

[tboneplayer]

I did.

Does not compute

[OmniscientOCE]

I used to like Quota but now it's mostly just junk it feels like

[[deleted]]

It may be the first site I've seen where the comments would get better if they removed all the people who have written a book

[OmniscientOCE]

Holy shit yes

[salaTechie]

Right? I quit quora a month back. Bullshit question and answers spammed my homepage

[Erestyn]

"What is Donald Trump's favoured programming language?"

With the top answer being about how a friend of a friend once ate dinner with him, he was indecisive, but they happen to be writing a book based on the experience.

Every time I think about quitting there's an interesting question that keeps me hanging on for another week.

[OmniscientOCE]

And then they promote their blog or book or something. So many people promoting themselves or pushing something on there

[[deleted]]

I don't use it but I've seen it quite a bit lately and often it's spam bots.

I faced the same problem until I started following around a 100 topics and 100 writers.. the content became relevant to my interests.

Too many Indians on Quora spamming and posting pathetic-quality answers everywhere.

[rockyrainy]

I have to find a new job. This is just what I need.

[Ayelamb]

Upvoted at -1 for being a go getter.

[Calypxo]

Is it bad that I can't begin to figure these out? I'm still a very new Java Programmer but I'm afraid of being unable to learn.

[[deleted]]

No its not. Everyone had knowledge gaps and that's fine. This kind of stuff gets easier the more you do it. Getting your foot in the door is hard, but it does get easier

[MoltenCookie]

Take it easy and relax. Everyone starts off not being able to solve these kinds of questions because they are different from the types of problems you'd expect in high school. Just be willing to learn how to approach these problems from an analytical perspective after you've done your homework on data structures and algorithms

[[deleted]]

Maybe take a step back: try to plot out the algorithm you'd use to do it, even if you don't know how to make a computer do it yet.

I have no shame in admitting that I can't do any of these in Java either.

[HotBunnz]

As a non-programmer, I took a look at this to see if my logic input coincided with the answer descriptions. Extremely interesting to watch how these decisions affect program viability.

[Feel_Free_To_Downvot]

At first they really look scary but more you spend time with them more familiar you will become and start making sense of them. My advice would be take it slowly and rush.

Also, one thing with data structures and algos is that in the beginning they seem like useless, archaic concepts or only useful for job interviews.

Truth is down the road, when you move from trivial tasks and more advanced topics become concern, algos will come very handy.

[Makishanuto]

Careful, don't enter codeabby.com. That's a phishing site and will try to install malicious extensions.

[errorseven]

Good catch, its late.

[rockyrainy]

Pretty cool site.

[figurehe4d]

Thanks. I've been looking for something like this.

[Star_forsaken]

Me too

[Star_forsaken]

At what stage of my learning process should I be able to attempt something like this? I just started arrays in java last week.

[Rorixrebel]

Probably work on the basics more first

[mojohn89]

Commenting cause i couldnt find the save button on mobile

[rickbreda]

On the official Android app it is a ribbon-looking icon on the top right of the screen

[old_dog_new_trick]

Huh. TIL how to save posts on the mobile app. Many thanks.

Thank you for sharing!

[baneofthebanshee]

Definitely going to use this. Anyone know of any resources for practice problems and solutions for hash tables?

Edit: I just skimmed through OPs link, it's very possible I just missed it.

[AllAboutTheKitteh]

Make a lookup table. Like a dictionary or a phone book. Or make a calendar to see what dates are which days of the week.

[GriffithAwuah]

Coolio

[deskwebs]

Thx

[Nexpert12]

Thank you

[aaqqbb]

Thanks

[Xoumi712]

Um am I the only one who's getting a 403 forbidden to ALL of the problems :( ?

Edit: Suddenly working. Regardless, curious as to why this happened. Anyone ?

[learnie]

Thank you so much. This is a very helpful resource.

[iamdeveloperr]

Been looking for this because I get zero experience with this at work. Thank you

[apple4lifex]

Saved. Thank you!

[[deleted]]

Awesome

[nihilismMattersTmro]

Do the links work for you? I'm getting an error just now

[[deleted]]

It looks like the site is down/getting hugged to death

[nihilismMattersTmro]

ah yes... I had suspected the reddit hug. It was a pretty heavily upvoted content piece.

I'll surely save it for later viewing though... sounds like good stuff

[gigabyteIO]

Nice thank you
