Problem Statement

You are given N strings.

The i-th string Si(1≤i≤N) is either Takahashi or Aoki.

How many i are there such that Si is equal to Takahashi?

Constraints

1≤N≤100
N is an integer.
Each Si is Takahashi or Aoki. (1≤i≤N)

Input

The input is given from Standard Input in the following format:

N
S1
S2
⋮
SN
​

Output

Print the count of i such that Si is equal to Takahashi as an integer in a single line.

Sample Input 1

3
Aoki
Takahashi
Takahashi

Sample Output 1

2
S2 and S3 are equal to Takahashi, while S1 is not.

Therefore, print 2.

Sample Input 2

2
Aoki
Aoki

Sample Output 2

0
It is possible that no Si is equal to Takahashi.

Sample Input 3

20
Aoki
Takahashi

思路分析：

本题需要来判断有多少个Takahashi，可以用ans来统计数量，用if来判断。

code：

#include <iostream>
#include <string>
using namespace std;
int n;
string s;
int ans=0;
int main(){cin>>n;for(int i=0;i<n;i++){cin>>s;if(s=="Takahashi") ans++;}cout<<ans;
}
