Did you consider the case when the total value becomes > 1 million?

Hello,

I have many WA's in this problem and I don't want make a guesses many more, I have question about "More than 1 million rule" (= if the value is above 1000000, that return 1000000). When should I apply this rule? Only in the end of computation ("Total returned"), and/or by every single Wager (second column of table in problem description), and/or by every Amount Won (forth column of table in problem description), or/and by making sum (row-by-row) of Total Returned? I tried many combination of this and I had always WA

I hope, that I wrote it understandly.

Thanks in advance!

I just considered it at the end of the computation.

Still getting WA... But dont know why is that.

Help me plz.....

Can anyone tell what I am wrong..i cannot find any case to bug my code.....Here is my code..

#include <iostream>
#include <string>
#include <map>
#include <queue>
#include <stack>
#include <algorithm>
#include <list>
#include <set>
#include <cmath>

#endif

#define REP(i,n) for (i=0;i<n;i++)
#define REV(i,n) for (i=n;i>=0;i--)

char ss[100];
int main()
{
int t,wage,num,n,cas=1,i,j;
double taka,r,to;
scanf("%d",&t);
while(t--)
{
scanf("%d %d",&wage,&num);
to=wage;
for(i=0;i<num;i++)
{
scanf("%d",&n);
if(n<0) taka= (100.0/(abs(n)));
else taka=(n/100.0);
r=ceil(wage*taka);
to+=r;
wage+=r;
}

if(to>=1000000) printf("%d $1,000,000.00\n",cas++);
else
{
i=j=0;
int too=to;
sprintf(ss,"%d",too);
int len=strlen(ss);
if(len>3) i=1;
printf("%d $",cas++);
for(int k=0;k<len;k++)
{
if(i && (len-3)==k) printf(",");
printf("%c",ss[k]);
}
printf(".00\n");
//printf("%s\n",ss);
}

}

return 0;
}

Thanks Advance..
