Typos in problems
Back to General discussions forum
"Thus the first sum-of-digits which is divisible by 10 is for number 19. The next is for number 27."
It is 28 actually, the example is correct tho
input data:
3
1
2
10
answer:
19 28 109
Good catch!
As a general question, is this where we would report minor typos with the text of problems, even if they don't interfere with the values or actual problem?
For example in the text for Problem 198 (Prn Hex Str) it is written "...a character whith higher nibble...". Just noticing a few very minor things like that. Not a big issue but if it's a simple matter of pointing out an unnoticed spelling/grammar error to get it fixed then just wondering if this should be the place to do that :)
Friends, Hi, and thanks for help!
Fixed 28 and with.
is this where we would report minor typos
Good question. The matter is we don't have better way, so doing this in forum should be fine. Perhaps, let me modify the title of this specific thread and somehow link it to problem descriptions everywhere a bit later. Then any further suggested corrections could be added here.
(at the very beginning there was a feature like, you know, select the typo and press ctrl-enter, but it was surprisingly unhandy)
UPD: added small link report typos on the right side, below the title etc (just below the title, when you read problem page).
Wow, I just noticed that "report typos" button and felt silly having missed it before... But I guess that was just a case of lightning-fast implementation!
I've also found 2 more small typos on Problem #284:
1) "...and feels it with further values..." should be "...and fills..."
2) "insde" should be "inside". Using ctrl+F might just be the easiest way to locate that one on that page.
Thanks!
A few more on https://www.codeabbey.com/index/wiki/basic-language-manual
Use ctrl+F for the following: 1) "identation" 2) "is is" 3) "loarithm"
Just some more typos, hope I'm not being annoying or anything with all the doubleposts...
This time on Problem #366 "Image Cutting".
"But you do not want to loose lose too much of your image. What is the biggest are area of the image you can cut..."
"Input data: First line will contain number of images to be cut. Other lines will contain width and height of the image WxH and the aspect ratio of the dsiplay display W:H separated by space.
Thanks!
Oh, so silly about this "feel/fill". I remember laughing at my boss who wrote "I don't fill well" and now, hooray, I made similar typo :)
About "identation" - I remember interesting story of similar mistake in documents of US (?) soldiers during WW2, which Germans corrected in the forged documents and thus their spies were uncovered by lacking typo Ctrl-F for "indentification" here.
Fixed these - and "lose", "area", "display" and "above" also. Thanks a lot!
hope I'm not being annoying
no, for sure :) it would be silly to add reporting link and then not to fix typos. on contrary, thanks a lot for your attentiveness! it is good to get rid of such silly mistakes, especially given that they may confuse people for whom English is not native language!
Don't feel bad! I'm not too familiar with Slavic languages or Cyrillic, but I know that English vowel sounds in particular are often hard to predict from their letter and vice versa, compared to many other languages having much more consistent mapping.
That is an amazing story from WW2!
I also found one more on #109 "Lucky Tickets" - concidered.
And I'm glad to help! Especially when helping is just making a note when I notice something :)
not a typo, but a math error, in #102 a convex polygon is wrongly defined as having all angles less than pi/2 while that should say less than pi.
sorry that ironically was a typo, i meant #105 in previous post and cannot edit it for some reason
Oh, thanks a lot! I wonder, how this problem was there for perhaps almost 10 years, solved by 900+ persons and only
now this silly mistake was noticed :) it is fixed now!
Editing of the post is limited probably to about 1 hour (for case that some significant information was shared which we don't want author to remove in future out of some fancy). No worry though, it was plain which problem is in question.
Also thanks for bringing attention here - obviously I missed couple of messages from Kevin aka moxieman above. Fixed
these too!
Rodion, thanks for Your quick response. Concerning my unability to edit, nevermind, this was definitely not a problem of the page, I was on an android device, which was buggy with edit forms. Today I edit another post and it worked fine!
Not a typo exactly, but in the Connect Four problem, the visualization link from the line "You may watch this visualization kindly created for us by our colleague Bloggermark to understand the game better.", is apparently broken.
Ultimately this doesn't impact the solvability of the problem, although now I'm curious as to what the visualization may have originally been!
On Problem 66, the link to openabbey.com redirects to ... something else.
This isn't as much a typo as it is a request for clarification.
I kept getting #49 Rock Paper Scissors wrong b/c the instructions were a bit ambiguous about what was expected.
The insturctions for the problem have no indiciation that all games provided should be processed and that the expected return value is the player who received the most wins.
When intially coding this, I got the impression that the first win was all that mattered and that the other cases were thrown in there to ensure the win check algorithm was working correctly.
Some better clarirification in the problem could prevent future confusion.
From the problem description: Input data will contain the number of matches played in the first line. [...] Answer should for each of matches specify whether first player wins (by value 1) or second (by value 2).
Sounds pretty clear to me.
go to https://www.codeabbey.com/index/task_view/two-printers and Ctrl+F "minumum"
Not really a typo as much as a suggestion, but in the Matching Brackets problem, the example input uses a word that's becoming an increasingly offensive term for Romani people.
It's nothing horribly offensive or anything, but I'd probably just replace it with another word to avoid raising eyebrows.
Hi and thanks for suggestion! No problem, let's replace it, though honestly it's the first time I hear the word "becoming increasingly offensive". That may lead to quite a bulk of literature and songs to be revised :) Wikipedia page you are refering is a bit confusing as it states the word is still used for self-identification in Britain.
As a sidenote I dare to lament how different the perception of what is offensive is in different cultures! E.g. popular "n-word" of US is considered neutral in my native language, while designating person as "white", "black" or especially "color" sounds rude.
Also thanks for bringing attention to this thread at all - now the several preceding issues are also corrected:
- vigenere-cipher-cracker link is corrected (problem is now on this site)
- broken link from connect four problem - removed :(
- very silly typo in the word minimun - corrected
many thanks for reports, Friends!
Oh yea, no worries! This shift is very recent relative to other linguistic shifts. I remember around even less than 10 years ago, people didn't really care about the word being used too much and normally used that word to refer to them (Altough, now that I think about it, usually when I heard the word it was used for a mysterious and spiritual mystic or fortune teller, which was probably the problem with it.) Nowadays, at least in the Americas, people are shifting towards the term Roma or Romani, Fleetwood Mac be damned. Not that I'm complaining of course, at the end of the day, if we keep people comfortable with what words we use, it's A OK to me.
Much love, mate!
Hi, I spotted three typos in one sentence in Problem 429. Currently, it says:
"Here average was checkd at moments 10.0 sec, 30.0 sec and 70.0 sec.",
I would rewrite the sentence as:
"Here, the average was checked at 10.0 seconds, 30.0 seconds, and 70.0 seconds."
Hi!
Problem #411: Elo Ratings
Players 2 and 1 are the highest-ranked, and so they play the first game of Round 1. Two random numbers are generated, R1 = 13336989 and R2 = 68938 which are multiplied to each Player's skill to yield 2629962985131 vs 125601589100,
so Player 2 wins and Player 1 loses. Their Elo Ratings change to 2010 and 1190, respectively.
Players 3 and 0 are the next highest-ranked, so they play the next game of Round 1. Two more random numbers are generated, R1 = 2017283, R2 = 809880.
Player 3 wins and Player 0 loses, so their Elo Ratings also change to 2010 and 1190, respectively.
Should be 1210 instead.
In Problem 235 (Train Merge Advanced), the wording is not clear that there are multiple acceptable answers.
As an example, for the test case given with two sets of 5 cars, there are 4 possible solutions that all give an answer of 212:
aabaabbbab aaababbbab aabaabbabb aaababbabb
With the full input data - there are significantly more.
Hi Friends!
To nalbe666 thank you - surprising that went unnoticed up till now :)
To JimmyCarlos - and thank you too, definitely it looks confusing without such clarification - I forgot it for some reason, sorry!
Hi. Problem 437: Elections and Happiness Example: 1973 6 4 0.945 0.731 1 0.542; 0.272 0.11 0.042 1; 0.335 1 0.045 0; 1 0.005 0.783 0.323; 0.247 0.014 0.664 1; 1 0.005 0.018 0.071; 0.022 0.058 0.294 1 Must be: 1973 7 4 otherwise 1973 would not be in the solution.
Greetings!
Hi Sergio, and thanks for correction! It makes me wonder how could I have been so inattentive :) should be fixed now, sorry
