C++

Implementation

Copy
#include <bits/stdc++.h>
using namespace std;

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

	int room_num;
	cin >> room_num;
	vector<int> rooms(room_num);

Java

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

public class CBarn {
	public static void main(String[] args) throws IOException {
		BufferedReader read = new BufferedReader(new FileReader("cbarn.in"));
		int roomNum = Integer.parseInt(read.readLine());

		int[] rooms = new int[roomNum];
		int totalCows = 0;

Python

Copy
with open("cbarn.in") as read:
	room_num = int(read.readline())
	rooms = [int(read.readline()) for _ in range(room_num)]

total_cows = sum(rooms)

min_dist = float("inf")
for unlock in range(room_num):
	dist = 0
	cows_left = total_cows
