Beautiful Days at the Movies

    Here is my Python solution! We check all the days and if the absolute value between the day and the reversed day is divisible by k, we add 1 to the amount of beautiful days.

    def beautifulDays(i, j, k):
    beautiful = 0
    for day in range(i, j + 1):
        if abs(day - int("".join(list(reversed(str(day)))))) % k == 0:
            beautiful += 1
    return beautiful
