i submit this program but i get (Time limit exceeded) error.
my program run in 3.000 sec.
Pleas help me to correct that.
my code:

#include “iostream”
using namespace std;

int main(){
unsigned int inI,
inJ;
int counter,MaxCounter;
do{
MaxCounter=0;
cin>>inI>>inJ;
cout< curpos=(curpos%2)?(3*curpos)+1:curpos/2;
counter++;
}
if (counter>MaxCounter) MaxCounter=counter;
inI++;
}while(inI<=inJ);
cout< }while(inI);
return 0;
}

It is a good solution:
#include
#include
using namespace std;

long cycleLen(unsigned long n)
{
int len=1;
while(n!=1)
{
if(n%2==1)
{
n=3*n+1;
}
else
{
n=n/2;
}
len=len+1;
}
return len;
}
void swap(unsigned long& i, unsigned long& j)
{
unsigned long tmp=0;
tmp=i;
i=j;
j=tmp;
}
int main()
{
unsigned long i=0,oldi=0;
unsigned long j=0,oldj=0;
unsigned long max=0;
unsigned long tmp=0;
while(cin>>i && cin>>j)
{
oldi=i;
oldj=j;
if(i>j)
{
swap(i,j);
}
for(unsigned long p=i;p<=j;p++)
{
tmp=cycleLen(p);
if(max {
max=tmp;
}
}
cout< max=0;
}
return 0;
}

if input is

10 1

output should be
1 10 20

The Common Lisp guy doesn’t realize that the judge will run the program on a larger set of numbers, thus vastly increasing the run time. Try 1…999999 instead.

I submitted your solution to the online judge and got the verdict wrong answer.

Moin,

vielen Dank für die Anleitung. Die Reinigung hat damit perfekt geklappt. Vorbereitung ist alles! Nach über 5 Jahren war da jede Menge Staub drin (das da überhaupt noch gekühlt werden konnte…?).

Viele Grüße

Jann
