This code is a solution found online as one of the public solutions for Leetcode #20. Valid Parentheses. The code checks if a sequence of parenthesis, brackets, and braces are valid in a single line. However, condensing the code into a single line makes it difficult to read.
Goals to Fix:
Rewrite the code to make it more understandable
