Parenthesis/Brackets Matching using Stack algorithm

Question

For example if the parenthesis/brackets is matching in the following:

({})
(()){}()
()

and so on but if the parenthesis/brackets is not mat

Answer 1

Here's a solution in Python.

#!/usr/bin/env python

def brackets_match(brackets):
    stack = []
    for char in brackets:
        if char == "{" or char == "(" or char == "[":
            stack.append(char)
        if char == "}":
            if stack[-1] == "{":
                stack.pop()
            else:
                return False
        elif char == "]":
            if stack[-1] == "[":
                stack.pop()
            else:
                return False
        elif char == ")":
            if stack[-1] == "(":
                stack.pop()
            else:
                return False
    if len(stack) == 0:
        return True
    else:
        return False

if __name__ == "__main__":
    print(brackets_match("This is testing {([])} if brackets have match."))
