That's why its better to print doubles like
Hope it helps.

My code gives TLE. Please help

#include <iostream>
#include <cstdlib>
#include <cstring>
#include <cstdio>

int main()
{
while(1) {
int dec=0,frac=0;
scanf("%d.%d",&dec,&frac);
long value=(dec*100+frac);
if(value==0) break;
double val;
unsigned long long ways[7001][11];
memset(ways,0,sizeof(ways));

if(value%5!=0) {
ways[value][10]=0;
val=value/100.00;
}
else {
value/=5;
int coins[11]={1,2,4,10,20,40,100,200,400,1000,2000};
for(int i=0;i<11;i++) ways[0]=1;
for(int i=1;i<=value;i++) {
for(int j=0;j<11;j++) {

unsigned long long type1=(j==0?0:ways[j-1]);
unsigned long long type2=(i>=coins[j]?ways[i-coins[j]][j]:0);
ways[j]=type1+type2;

}

}

val=value/20.0;
}
printf("%6.2lf%17llu\n",val,ways[value][10]);
}
return 0;
}

Why Compile error???
I can't imagin about this....... plz notify someone about this.......

I think 'void main' is the problem. You must use
Hope it helps.

I've forgot about this but now also it gives me PE

What can i do plz .............

Edit : The correct format is given below.

But that line first i submitted
It was a presentation Error......
After that i gave this one........

I haven't understood you fully. Why did you use %10lld?

I mean first field width is 6 so to set last field width to 17 it's need to add more 10 width so that i printed that.......

At first i printed 6 and 17 but that was also PE

So what can i do?

Give me some trics.......

Try this one (Sorry, I was wrong ) Hope it helps.

I cannot understand why this was a PE ......... It should have WA .......
Am i wrong?? Plz give some info about it.

Your previous code was correct except the formatting. The 1e-7 was given for safety, nothing else. Check carefully, you used %17lld but there was a space behind it. So, it was PE.

Would it be the reason of wrong answer?
Or there might be other errors in my code?

Please give me some more tricky test cases.
Thanks!

I can't think of any tricky case. You can post your code.

Here's my code.
I use the same method as problem 357.
I really don't know where could be wrong...
Thanks for checking it for me!
