What is wrong with this code?

#1

#include
using namespace std;
int count(int n)
{

if(n<=2)
{
	return n;
}
return count(n-1)+n-1*count(n-2);

}
int main() {
int t;
cin>>t;
while(t–)
{
int x=0;
int n;
cin>>n;
x=count(n);
cout<<x<<endl;
}
return 0;
}

@mayank10 I don’t think there is something wrong in the logic but it may give wrong answer depending upon the values of n, so prefer to use long long int before submitting.

Use long long instead of int in dp
