C :

#include<stdio.h>

int main()
{
	int n;
	scanf("%d",&n);
	char a[n],i;
	for(i=0;i<n;i++){
		scanf("%s",&a[i]);

				s++;
		}
		break;
				}
				printf("%d",n-s);
	
	



return 0;
}

C++ :

#include<bits/stdc++.h>
using namespace std;
int main(){
	int n,i,c=0;
	string s;
	cin>>n;

		} 
		if (s[0]>='U' && s[0]<='Z') {

		}
	}
	cout<<c<<endl;

	return 0;
}

Java :

js=0
for i in range(1,n+1):
    sr=input()
    if (sr[0]>="A" and sr[0]<="G") or (sr[0]>="R" and sr[0]<="T"):
        js=js+1
