C++

Implementation

Copy
#include <iostream>
#include <vector>

using namespace std;

int main() {
	freopen("bcount.in", "r", stdin);
	freopen("bcount.out", "w", stdout);

	int cow_num;

Java

Implementation

Copy
import java.io.*;
import java.util.*;

public class BCount {
	public static void main(String[] args) throws IOException {
		BufferedReader read = new BufferedReader(new FileReader("bcount.in"));
		PrintWriter out =
		    new PrintWriter(new BufferedWriter(new FileWriter("bcount.out")));
		StringTokenizer initial = new StringTokenizer(read.readLine());
		int cowNum = Integer.parseInt(initial.nextToken());

Python

Copy
with open("bcount.in") as read:
	cow_num, query_num = [int(i) for i in read.readline().split()]
	holsteins = [0]
	guernseys = [0]
	jerseys = [0]
	for _ in range(cow_num):
		holsteins.append(holsteins[-1])
		guernseys.append(guernseys[-1])
		jerseys.append(jerseys[-1])
