zacharyleung - what version of gcc do you have? Do you happen to use any command line switch? Your problem is not with the compiler though, but with linker (ld). Ask your system administrator about it - it seems that gcc is installed inappriopriately. Your TMP environmental variable possibly has a ...

Ok, I changed the program to:
[cpp]
#include <iostream>

using namespace std;

int main() {
int i;
cout << "hello" << endl;
cin >> i;
return 0;
}
[/cpp]

But I get exactly the same problem!

Just a note: I'm not doing this on my own computer. I'm SSH-ing to a remote computer (a university comp ...

This is a really strang error that I get! Any idea what's wrong?

[cpp]
#include <iostream>

int main() {
int i;
cout << "hello" << endl;
cin >> i;
return 0;
}
[/cpp]

I tried to think about it, but I really have no idea how to do that. Since we use the square root of x^2 and y^2, won't that always be a float?

I'm quite sure my code is correct, could anyone tell me what's wrong, cos I keep on getting WA....

[cpp]
#include <cstdio>
#include <cmath>
#include <cstring>

#define DEBUG(var) cout << #var << " = " << var << endl;
#define LINE cout << __LINE__ << endl;

I've gotten an AC for this question. :D But my solution takes about 6 seconds to run, which is a lot longer than the fastest solutions (about 0.15 seconds) Any suggestions as to how to make this faster?

[cpp]
#include <cstdio>
#include <climits>
#include <cstring>

#define DEBUGI(var) printf( "%s ...

I was getting stuck on this problem, and I finally figured out why I was getting WA. The reason was that if the bit map contians more than 50 characters, they would like the answer to be something like the following:

D 3 30
DDDDD01D01DD01D01DDD01D01DD010DDD10D10DD10D10DDD10 ...

There are quite a few questions where we are required to print the lexicographically smallest answer. Is there a good way in general to get this smallest answer? Problems that are like this include 116, 10026...

Yeah, that was definitiely helpful, thanks!

Normally when I write programs, I log on using a SSH client to a remote server and I use emacs to write my program. Sometimes I accidentally hit C-z which suspends my currently running application. I can't figure out how to restart it, does anyone know how I can restart my suspended application ...

Ah, ok, thanks!

I believe it's 2^31 - 1. The thing is when I want to write code like the following

min = Integer.MAX_VALUE
for( i = ...)
if( min < value )
min = vale

So what is the maximum value, or where can I find it?

Thanks!

Just wondering, what is the significance of the number 65535 in this line?

[java]
while( delim.indexOf( (int) c ) != -1 && c != 65535 )
[/java]

Thanks.

This is my first post! :)
Anyway, I know this is a pretty simple problem, but I can't figure out how to read in the input correctly. I'm pretty confident that my algorithm works. Because I can't always read in the input correctly, I'm having problems with a few other problems too. I'd appreciate it ...
