Please help me.
I really confuse.

I got WA, but I can't make out where is wrong in my code.
This problem looks very easy, and my code actually pass many test cases.
I'm really going to get mad. :evil:
plz help me someone!

Here is my code.



#include <iostream>
#include <string>

using namespace std;

#define MAX 32

char result ...

hi randomtaiwanese.

I think you don't need to use such many function, sould use the Display Number template instead.
Try to draw some Display Number by hands.

For example, when the Number is 3 and Size is 1, it is represented by follow.


.-.
..|
.-.
..|
.-.


"." represents a space.
Then you ...

try this.
You should output "Yes".

hi vadiu.

Problem says, "0 <= L <= 50".
So the input maybe a zero.
This is that shamim has also said.

hi wipper.

Your program is almost always correct, but maybe have a bit bug.

Try following case(X):

3 3
1 1 1
1 2 2
1 3 3


Your output is 1, and it is correct.

But try following another case(Y):

5 2
3 7
8 10
5 2
9 11
21 18
8 6
5 2 20 1 30 10
23 15 7 9 11 3
40 50 34 24 14 4
9 10 11 12 13 14 ...

hi wolf, and tetuya.

My ID changed 47401 to 47400....

Please return My ID, anyone, please....

hi sohel.

I used Floyd too, and got WA.

So I check following test case:

6
0 1
0 2
1 2
2 3
3 2
3 4


Output shoud be follow:

matrix for city 0
0 1 -1 -1 -1
0 0 -1 -1 -1
0 0 -1 -1 -1
0 0 -1 -1 -1
0 0 0 0 0


But My first program outputed follow:

matrix for city 0
0 1 -1 -1 4
0 0 -1 -1 2
0 0 ...

hi yiuyuho.

I have got WA, so I checked output for your input.

Follow case:
390625 65535

I couldn't get any answer.
It's more than probable that program run for endless loop becase it can't find the value of N.
But I got Accept now.

I think your input is invalid.
This problem is undifficult, but ...

hi kisow.

I edit my replay and fix my mistake.
Thanks for your sharp shooting.

hi.
I got ACCEPT, and I'll give you test data.

hi.

Although I haven't read probelm 751 yet, there is a clear bug.
[cpp]
int y=0;
int z=6/y;
[/cpp]
This code always set Y for 0.
You cannot divide by 0 anytime.
So, you recieved SIGFPE, I think so.

If I'm wrong, so sry.

hi.

I got accept after some WA, but I think this problem is easy and simple.
Cause of your WA might a very little bug.

And...
Thank you for your reply :D :D

I read this following passage.

and X1,...,Xn will be positive integers less than 100.

and , 999 1 999 is invalid input,isnt it?
Yes ...

I created the Big-num library by c++, too.
I use array of short for Big number.
Becase short value has maximum 4 digit(and it's not character, but in decimal).
I make recommendation of using an array of short to you.
But array of short is not easy to output ... you should be careful for zero digit ...
