#include <iostream>
using namespace std;
int main()
{
int n, m, lx = 0, jx = 0, zc = 0;
char x;
cin>>n>>m;

for(int i = 1; i <= n; i++)
{
    for(int j = 1; j <= m; j++)
    {
        cin>>x;
        if(x == '*')
            ++lx;
        if(x == '_')
            ++zc;
        if(x == '&')
            ++jx;
    }
}

cout<<lx<<endl;
cout<<jx<<endl;
cout<<zc;
return 0;
