Problem Statement

You must implement the count_low_high() function. Its parameter is a list of numbers.

If a number is greater than 50 or divisible by 3, it will count as a high. If these conditions are not met, the number is considered a low.

At the end of the function, you must return a list that contains the number of lows and highs, in that order.

In case the list is empty, you may return None.

Sample Input

num_list = [20, 9, 51, 81, 50, 42, 77]

Sample Output

[2, 5] # 2 lows and 5 highs
