## Discussion of Problem 1705. Gangster Hares

why time limit on test#3?
Posted by lolpwnZzzz 22 Nov 2010 00:06
my code:

// 1705.cpp : Defines the entry point for the console application.
//

#include <iostream>
using namespace std;
double sqroot(double);
int main()
{
int t;
cin>>t;
long long int input[50001];
long long int output[50001];
for(int i=0;i<t;i++)
{
scanf("%lli",&input[i]);
long long int k=2;
k=sqroot((double)input[i]);
if(k<1) k = 1;
while(true )
{
if(input[i]/k==(input[i]/(k+1)))
break;
else
k++;
}
output[i]=k;
}
for(int i=0;i<t;i++)
printf("%lli\n",output[i]);
return 0;
}

inline double sqroot(double n)
{
double begin=0;
double end=n;
double res=0;
double precision=0.1;
while(end-begin>precision)
{
res=(begin+end)/2;
if(res*res>n)
end=res;
else
begin=res;
}
return res;
}
for n=10^18 loop execute about 30000 times
May this be the couse of time limit??
