Comparing conditions in shell scripts - what's it all about?

The article titled "Testing Brackets" by J.M. Mejia discusses techniques used in programming to evaluate the correctness of brackets in expressions. The author presents an algorithm implementation that effectively checks if the brackets are used properly in a given expression. This algorithm compares corresponding pairs of brackets and utilizes a stack data structure, allowing for easy management of both opening and closing brackets. Additionally, the author discusses possible expansions of the algorithm, such as supporting different types of brackets, making it more versatile. The entire process is detailed, making this article a valuable resource for developers involved in the analysis and validation of mathematical expressions and other data.
