C++ :

#include<bits/stdc++.h>
using namespace std;
int main(){
	long long n,a[n+5],m,sum=0;
	cin>>n;
	for(int i=0;i<n;i++){
		cin>>a[i];
	}
	cin>>m;
	for(int i=0;i<n;i++){
		if(a[i]==m)sum++;
	}
	cout<<sum<<endl;
	return 0;	
}

Python :

# coding=utf-8
c = 0
n = input()
ls = input().split()
m = input()
for i in ls:
    if m == i:
        c += 1
print(c)
