You're welcome.

Sometimes, the most stupid mistakes are the ones that make us to waste more time (that's my own experience).

Now it's time to try a new problem

I find the printf line rather worrisome. What are exactly those characters you're printing? I see a couple of tildes, not ``

Hello,

Can somebody post an input and output ?
Thanks !

I would also appreciate it if someone were able to post some IO cases, and in particular some one for which my program gives WA. I've tried with the sample IO and also with the ones I found in these forums, and in all cases my program gives ...

I tried with a straight-to-the-problem solution, i mean i made a procedure that returns 1 if a given number is ugly and 0 otherwize. Well as you can suppose the result needs a lot of time.
The function is that:

If some one can find a way to speed this up. I will be greatfull for help ...

Hi there,

I agree with people that claims that this problem is really hard to solve in general given the problem description constraints.

Any of you has got an algorithm (deterministic, I mean, not based on random node choices that may or not lead to the actual solution) that solves this problem ...

printf ("Hello, world\n");

I've thought that a possible method to improve efficiency in this algorithm could be to store not only cycle values for numbers as they are being computed, but also the maximum of each one of the input intervals.

This could help to save time if further intervals may be ...

One claims that just replace all " with `` and ' ' and you can get AC,

Yes, just replace that, but also remember to leave unchanged the rest of characters. Are you sure you do so? Do you believe that your program copies to the output all input characters others than ", including ...

Where should the below code added and what's the purpose?
I know how to output the spaces but I still don't manage to output line by line, I can just output a single continuous line, what else should I add?
cout << "<<" << s << ">>";

Let's see, hahahaken... :roll: That line is not only ...

I have edited my code and submit a few times, but still wrong anssssss..., here's the lastest one, pls help :cry:
P.S. I've referred to the AC codes posted above, I think mine is similar to that, but I don't know what's wrong with mine
P.S.2 I have discovered that the single quotes should remain ...

This problem is extremely easy if one thinks in term of characters rather than lines.

WARNING: One program that gets AC follows (maybe not the best one in execution time, but AC). Do not read it if you still feel this problem as a challenge.


Removed. Looks like it's not a good practice at all ...

Hi, there.

This problem description says that values n and k (respectively, number of options for programmers and budget for a given programming division) will be greater than or equal to zero.

I find that allowing any (or both) of these values to be zero this rather confusing for several reasons ...

Hi friends,
someone have inputs and outputs AC to this problem?

thanks in advance.

Hi, adelar.

It's not a very large set of I/O, but could be helpful, so I drop them right here.

Input:
8
0000X000
X0000000
0000X00X
00000X00
00000000
000000X0
0X000000
000X0000

8
X0000000
000000X0
0000X000 ...

Hope you'll get AC soon :D

Well, after modifying my program to consider more than one test case, I got AC.

It's certainly annoying to get stuck in one problem just because its description is clearly incorrect and confusing... :x

I shall complain about this.

Regards, and thank you again for ...

Thank you for the tip and your good wishes.
