Tell me where is the error?


int main()
int num,a,b,i;
long long unsigned int c;

printf("The Fibonacci number for %d is %llu\n",num,c);
return 0;

u must use big integer to solve this problem...
try these:

Code: Select all


Code: Select all

The Fibonacci number for 5000 is 3878968454388325633701916308325905312082127714646245106160597214895550139044037097010822916462210669479293452858882973813483102008954982940361430156911478938364216563944106910214505634133706558656238254656700712525929903854933813928836378347518908762970712033337052923107693008518093849801803847813996748881765554653788291644268912980384613778969021502293082475666346224923071883324803280375039130352903304505842701147635242270210934637699104006714174883298422891491273104054328753298044273676822977244987749874555691907703880637046832794811358973739993110106219308149018570815397854379195305617510761053075688783766033667355445258844886241619210553457493675897849027988234351023599844663934853256411952221859563060475364645470760330902420806382584929156452876291575759142343809142302917491088984155209854432486594079793571316841692868039545309545388698114665082066862897420639323438488465240988742395873801976993820317174208932265468879364002630797780058759129671389634214252579116872755600360311370547754724604639987588046985178408674382863125

My output is correct, but in server CE (compile error).

"Compile error". WHY?

Code: Select all


Thanks Jan (for help me with 1st error "compile error").
Please, help.

Code: Select all

int borrarint(bigint *a)

Code: Select all

void borrarint(bigint *a)

Now WA, but it is another problem (my problem).

Thanks Jan.

My 2nd error was:

Print fib(0)="" ------> Print fib(0)=0

Now my problem is AC.

with the fo.llowing code i got a compile error which is running perfectly on my comp.

import java.util.*;
import java.math.*;
class Main{
private static BufferedReader stdin =
new BufferedReader( new InputStreamReader( ) );
public static void main (String args[])
Main myWork = new Main();

void Begin(){
int j,number=0;
String input=null;
while (true) {
input = stdin.readLine();
number = Integer.parseInt( input );
}catch(Exception e){
BigInteger a = new BigInteger("0");
BigInteger b = new BigInteger("1");
BigInteger c = new BigInteger("0");
System.out.println("The Fibonacci number for "+number+" is "+c);

Here are the compiler error messages: Can't find default package `java.math'. Check the
CLASSPATH environment variable and the access to the archives.
1 error

someone plz help.

Currently UVa's judge doesn't allow to use java.math.BigInteger.
You have to implement bignums yourself.

edit: this is no longer true; judge now uses jdk 1.6.

When you use initialized arrays like this:

Code: Select all

#define N 5002
int fab[N][N]={{0}};
the compiler might put the array in the initialized data section, and as a result produce an executable file of size about 100Mb of mostly zero bytes. Probably that's too big for some compiler's module and it crashes with signal 25 (SIGXFSZ, File size limit exceeded).

If you don't initialize it, compiler will put the array in uninitialized data section, memory for which will be allocated at run-time, and then filled with zeros, too - so don't bother initializing globals with 0s.

Anyway, default memory limit for programs is 32Mb at this judge, so your program won't be accepted.

how much digits the 5000th fibonacci number takes??
what is urs minimum time and memory to solve it??
how is it possible to solve it in 0.00 sec and min mem??

advanced thanx!!

simple, simply the best!!

Nobody has solved it in 0.000 seconds.

There is something unusual with this problem. I created an input file for all numbers between 0 and 5000 inclusive and ran my solution for it. On my PC it worked ~3 seconds. But Judge says it's TLE.
But I managed to get AC (thanking little joey). (His) Hint for PAS programmers: don't use write to output. Output everything in ansistring and then just writeln it.

I have written the following code for this problem:

Code: Select all

-- Deleted --
I have tested using the test cases in this thread and found myself correct. However, I submitted to the judge and it says WA. what's wrong with my code?

Try this case..

Code: Select all

See the result of '4997'
I don't know why this is happening..
