I am trying out this problem on Codeforces. https://codeforces.me/contest/478/problem/C

I get the correct output for the test case 5 4 3 as 4 in my system, which is also the output of the sample test case.

Here is my code. Could someone please tell where I am going wrong ?

#include<bits/stdc++.h>
using namespace std;
typedef long long ll;
int main()
{
	int r,g,b;
	cin>>r>>g>>b;
	int mini=min(min(r,g),b);
	int ans=mini;
	int maxi=max(max(r,g),b);
	int sma;
	if(r!=maxi && r!=mini)
	r=sma;
	else if(g!=maxi && g!=mini)
	g=sma;
	else
	b=sma;

	if(maxi > 2*sma)
	{
		ans+=sma;
	}
	else
	{
		ans+=((sma+maxi)/3);
	}
	
	cout<<ans<<endl;
	return 0;
}

But the online judge shows my answer as 3 and hence failed in the first test case.
