hey! i was trying to solve this problem but i am continuously getting WA on sample test cases itself.here's my submission...can someone please point a bug in my code..
hi!i was solving this problem.it's strange that this submission1 got TLE while when i used set instead of visited array to keep track of colors the same code got AC.My AC code.Can someone please explain me why??
How can i solve this question? i wrote the following code but it fails for larger test cases:
#include<bits/stdc++.h>
using namespace std;
int main()
{
while(1)
{
long long sum;
cin>>sum;
long long int n=sqrt(sum);
int h=0,len=999999999;
for(int i=n;i<=2*n;i++)
{
//printf("%d\n",i);
int fh=(i*(i+1))/2;
if(fh>sum)
break;
if(fh==sum)
{
if(len>n)
{
cout<<len<<endl;
h=i;
len=i;
}
}
long long int rem=sum-fh;
long long int a=2*(i-1)+1;
if(a*a-8*rem>=0)
{
long long int r=(a+sqrt((a*a)-(8*rem)))/2;
if(2*rem==r*(2*(i-1)+(r-1)*-1))
{
if(len>i+r)
{
len=i+r;
cout<<len<<' '<<i<<endl;
}
}
if(a>sqrt(a*a-8*rem))
{
long long int r=(a-sqrt((a*a)-(8*rem)))/2;
if(2*rem==r*(2*(i-1)+(r-1)*-1))
{
if(len>i+r)
{
len=i+r;
cout<<len<<' '<<i<<endl;
}
}
}
}
}
printf("%d\n",len);
}
return 0;
}
please help? Edit: sorry, the question was not visible earlier.Now it's visible.
