The interactive runner links stdin and stdout but does not touch stderr. I had
success printing to stderr throughout your program to print useful, readable
information.

Hello all,
I'm looking for a method for debugging my solutions to interactive problems
using a debugger. In particular, I wan't to be able to set breakpoints in
my C++ solution, and have them trigger when it reaches that point. The
problem arises because I call the interactive runner, and pass
The approach of greedy assigning out-of-order fails in this case:
J1: 0 2 (Assigns to C)
J2: 1 4 (Assigns to J)
J3: 8 10 (Assigns to C)
J4: 3 10 (Now Impossible because C is busy 8-10, and J is busy 3-4.)
However swapping J1 and J2 so that J is busy 0-2 and C is busy 1-4, now J
is free to do

I think CJJCC should also be accepted.

Your solution simply does not work.
You need to process the activities based on their start time (or end time)
instead of the order given in the input.

Turns out that it *was not* a Runtime Error. Thanks to @porker2008 I was
able to fix my answer by first sorting the activities. Apparently "Case #3:
CJJCC" is not a valid alternative for "Case #3: JCCJJ".

Not sure why you need to call *cin.sync()* in your code.
You shouldn't do that because everything you haven't read from *STDIN* will
be lost at that point.

How do interactive problems work?
Just as in non-interactive problems, you will receive input from stdin and
print output to stdout. Our system will do the job of directing your output
stream to the judge's input stream, and pointing the judge's output stream
to your input stream. However,
The greedy approach you're using doesn't handle all cases, eg
0 1

I am maintaining an archive of C++ solutions for 2020 problems. Feel free
to check out the link below if you have questions regarding a problem. Even
if you are not using C++, reading through the comments may help you solve
the problem in your preferred language. As time permits, I will be

Hi, I'm trying to resolve Parenting Partnering Returns, but I'm getting WA.
The problem is that for me the results are OK.
My idea to solve that is to create a class named Activity and override the
method equals, in the method equals I will check if the activity A
intersects with activity B.
Hello everybody, I would like to share my solution with Python 3. Its
pretty long code, but it passes the three cases. I dont know about you, but
this problem was really challenging and took a lot of tries to get it right.
Basically first I check 2 pairs that Bits[x] == Bits[B-x] and

Hi everyone,
I have some issue when testing the interactive problem ESAb ATAd with the
provided testing tool.
I coded my solution in C and the testing tool doesn't run because of
'printf'. It waits in infinite loop.
I ran my code separately and it works just fine.
To investigate this issue, I
Here is the code in C++.
Can you please clarify - When testing on local machine is it sufficient to

standard input and output. My program works when I enter input manually
from keyboard. I am using cin for reading No of

To be more specific, the following line throw a runtime exception
*A.sort()*
The exception message was like *AttributeError: 'map' object has no

To fix this, you simply convert A to a list. See my code below.
