Hope it Helps
Keep posting !!

It's Really Strange ... Then So much my code will like this hiks ... Can you explain what's going on ?

Hi !! jhonny_yang I Submit your code and get AC the problem its ok, I think that if you submit the code by mail maybe there are problems, try to submit http://acm.uva.es/problemset/submit.php its better, I'm sure that your code its ok

I got WA .. but I don't know why???
Please help me ... !!!
Thanks...

[cpp]
//http://acm.uva.es/p/v4/443.html
#include <iostream.h>
unsigned long int humbles[5843];
int humble;

void AddtoList(unsigned long int No)

humble++;

if(No>humbles)
{
//Shifting
for(j=humble;j>=i+2;j--)
humbles[j]=humbles[j-1];

humbles[i+1]=No;
return ;
}
}

}

bool NotInList(unsigned long int No)
{
for(int i=1;i<=humble;i++)
if(humbles==No)
return false;

int main()

Thank you...I got AC !

btw,
[c]
if (times[1] < times[0])
times[1] = 1;
times[2] = humble * 5;
if (times[2] < times[1] || times[2] < times[0])
times[2] = 1;
times[3] = humble*7;
if (times[3] < times[2] || times[3] < times[1] || times[3] < times[0])
[/c]

is for checking for overflow

Hi willy, let me give u a good news, ur code got Accepted after I add something in it......check it out......

if(n%100==11 || n%100==12 ||n%100==13)
{
printf("th");
}

add it in the code and get acc and ofcourse make it the 1st case, I mean put it in the top......

Goodluck.......

thanks!

I am getting WA in this problem although i have done everything rite.
All the suffixes are correct and the values for different inputs is also correct.
But I dont know why its giving WA.
Plz help me.

Try this input: Your output: My AC program output: Good luck...

Thanx a lot.
But can u explain why this happened? My program shud generate the numbers which are 2^a*3^b*5^c*7*d.
But it isnt happening in some case. Can u explain why is this so?

I'm not sure how it works in C++, but in Java some of those would overflow - it would multiply two ints and then cast them to a 64-bit (long long in your case)

I guess you check it here: but overflow doesn't have to give you a negative integer (I think) and it looks wrong for some reason

Maybe that's a problem?

that means if i change the condition to (pro<(long long)2000000000 && pro<(long long)0)

then wud it be ok?

... neways i think that this cud have been the problem bcoz i changed my variables from int to long long and now the program gives correct output.
i havent submitted it yet but now it might be accepted.

Cast to long long *before* multiplying and then it should work.

Of course, if you use long longs everywhere, it eliminates that problem.
