# Unlocking the Mystery of Open Lockers

## How can we determine which lockers are open after the students have passed through the building?

Write a program to find the answer and display all open locker numbers separated by exactly one space.

## Solution:

To find out which lockers are open, we need to know the number of students and lockers. Here is a Python program to simulate the locker changing process:

## Step-by-Step Explanation:

1. Initialize an array of lockers with all set to "closed".

2. Iterate through each student and toggle the state of every nth locker, where n is the student's number.

3. Loop through the locker array and print out the numbers of any open lockers.

4. Adjust the `num_students` variable to match the actual number of students.

5. The `open_lockers` list comprehension creates a list of open locker numbers.

6. Run the program to output the open locker numbers separated by one space.
