The United States of America Computing Olympiad (USACO) is a computer programming competition primarily for secondary school students in the United States. The USACO offers four competitions during the academic year in four increasingly difficult divisions: Bronze, Silver, Gold and Platinum. Participants advance through the levels by performing well in their current division. A week-long summer training camp is held where four students are selected from a group of 24 finalists to represent the United States at the International Olympiad in Informatics (IOI). All expenses are paid for the training camp and competition at IOI. The USACO was founded in 1992 by Don Piele at the University of Wisconsin-Parkside and is currently maintained by director Brian Dean at Clemson University and a dedicated volunteer coaching staff.
Copied from usaco.org:
The USACO 2020 US Open contest is available March 27 through March 30. Participation is free, and open to all, although only high-school (pre-college) students in the USA are eligible for selection as finalists to attend the USACO training camp and to compete for the USA IOI team.
The contest is available in four divisions: bronze, silver, gold, and platinum. All returning participants start out in their former divisions, and new participants start out in the bronze division. The contest is for individuals only, not teams.
"Yeah I got perfect score on us open, which is nice"
You're a legend bro. Hope I can get even half of your coding skills some day.
@Andrei Serban Orice aplicatie reala se bazeaza pe asa ceva lol
@Andrei Serban Inteleg ca incerci sa pari inteligent, dar nu oricine poate participa la astfel de concursuri
@@TutorialeGratuite As long as you put your heart into it you get there. William was in Platinum in high school and I estimate he started coding from late elementary/earl middle school. It shows if you put your mind and truly enjoy coding you can get there in 5 or so years. Myself, I don't think I have "fun" coding but I hope to achieve gold in high school.
@Andrei Serban Ia tu 300 de puncte in prima la proba la IOI si dupa comenteaza.
I don't know jack about programming and I have no idea how I found your channel. However, I love all of this stuff. Keep up the good work. Subbed.
lin can you make a complete video on data structures ?
I am having trouble figuring that out..
Please
For the first time ever he uses an IDE lmao
What was he using before?
@廿 is that not an IDE?
@@jackadams8648 vim doesnt have debugger or build automation tool, its a great text editor though
Still waiting for him when he uses dark mode. I can die peacefully then.
0:27 can't help noticing the twice logo on the left
How do people come up with these problems?
Remember this: Human beings are faster in creating problems than actually solving them
Previous winners of contest collaborate to create new problems in contests. They also take some problems from computer science research papers
They are people who use to do usaco in past or do research
Man this looks like some hard problems

William: "This one has to work."
USACO: Sorry
4:33:31
William: "This is the last time I'm submitting."
USACO: WTF

William: "All these stupid reasons prevent you from solving this. "
USACO: There you go!
4 hours well spent
Please make a vidoe on competitive programming setup
I saw in one of his video, he was just using a laptop. I’m not sure tho.
All he uses is a laptop!
Why Dev-C++ this time? :P
RUclips has gone crazy! The video was uploaded 6 hours ago and the comment was written a month ago.
@@shujamukhtar4563 I think it has only just been made public, so it sets that as the upload date for some reason.
@@exildur ohhh
Lmao
@@exildur, if it wasn't public, how was the guy able to comment a month ago?
can u make a vedio on how to use gvim iin regard to competitive coding , thanks in advance !!
Does this mean ur qualified for IOI
He's qualified already.
Can you pleassse make a video on your IDE and setup? I've been doing usaco for a while but so many times I get the right answer on my computer and the wrong answer on usaco, and I never know why.
Are you going to do any live stream any time soon?
pl Can you make a video on how to setup and use Vim??
i dont know whats happenning but I know youre doing great
hi william lin, i am looking into segmentation, can you make a video about it please
Like só much this videos, bring more to us
I suppose you know golang. Do you think it's faster than c++ as it's compile time language too.
I need some tips buddy. I am a high school student from india. I want to ask how should i start programming like should i take a online course or join a bootcamp so that i can become a programmer like you
Why don't you make this video public?
It's in my playlist so people can find it from my channel if people want to. I think that most people aren't interested in this, and if I make too many videos public, people might have a hard time finding what they want.
@@tmwilliamlin168 and why video is public now?
Subhan shareef cos he is smoken
@@subhanshareef939 USACO is not some random contest, so I thought that I would make this one public and keep the other ones (JOI for example) unlisted
I understood nothing but it felt good. :-)
Bro could you make a video about how to see the answer in Google forums? Pls you will be viral
How can I learn to code like this
Which google chrome theme are you using?? anyone know about it?
hey , can you tell me why did you multiply it by inverse of 2?
how did you comment a month ago?
@@gauravjawla maybe because it was unlisted, william mightve posted a link in some cp site and people were able to comment before he video was published.
Correction: yes, he set this video to unlisted so people cant comment until he made it public
I see this time you are using dev cpp . But what cpp text editor do you generally use while doing competitive programming ?
He uses VIM
gvim
which program do you using
What machine are you using to film this videos?
did you stop coding ? no more videos on your channe
what rank are you in LOL?
he made it to IOI, which is top 4 in the country. its above camp, and that is above platinum.
Hi William, can you make a video about how to start competitive programming? Which books do you recommend?
Indeed he already made one
reupload?
I think so to coz I can see old comments
I guess he just made it public. It was an unlisted video before
100 k !!!!!
hey, what color scheme do you use in vim?
Default
Why the hell are some of these comments saying 1 month ago and it was just posted lol.
what keyboard do you have?
Say please, what painting app are you using?
In the slight case that you’re not joking. He is using OneNote. A software for taking notes
Jabree Thanks 👍
You should do a speed run of the google foobar challenge.
What program that you use in drawing
Onenote
What's your discord link? Can I join?

A palindrome is a number or sequence that reads forwards the same as backwards, eg 12321.
While it has not been proved, there is a conjecture that numbers can be made palindrome by continuing to add the reverse of a number to itself until the number becomes a palindrome. For example if we start with 19, we can continue as follows:
19 + 91 = 110
110 + 011 = 121
which is palindrome.
There are however some numbers that we have yet to find a terminating sequence for.
You are required to write a C program that accepts a number as input from the user, and applies this algorithm to obtain the smallest/first palindrome number. Once you have this palindrome, you must output it to the screen. You must only write this single number as output. If the sequence doesn't yield a palindrome before the number exceeds 11 digits then you must write the phrase "NO SOLUTION" without quotes to the screen.
The following is an example of how your program should operate
Example input:
19
Example output:
121

I can help. Seems easy. Reply me if you want solution with code
I do need a solution

Русские! Го лайки накинем чтобы все думали что тут я написал что-то умное?
Может вам и не интересно, но мне очень нравится наполеон который делает моя бабушка, а ещё я обожаю жареное мясо.
What ide are you using for this? This is not GVIM right?
dev-c++
WHy Dev-c++?
RUclips algorithm sucks. I do not understand one bit. WHY....
do you use qwerty or dvorak or something else?
спасибо
Oh you use this Dev cpp this time, every mainland oier uses this Ide Lmao
