Chemical Analysis
As the input you'll get a chemical formula and a number limit. Your task is to create a sequence of chemical elements, which are in the amount of >= limit in the formula.
Pay attention, that in some formulas brackets (), [] will be used. They have different meaning in chemistry, but from the point of calculating number of atoms they both work the same way - as ordinary parenthesis in mathematical expression. This article will help you to open the brackets and don't make mistakes while counting.
Input: Chemical formula as string (str) and the limit number of atoms as integer (int).
Output: List of certain chemical elements, sorted in the alphabetical order.
Examples:
assert atoms("C2H5OH",...
