Solution Review: Reverse Parentheses

Explore how to solve the reverse parentheses problem using a stack in Go. Understand how to handle balanced and unbalanced parentheses, calculate reversal counts, and analyze the algorithm's time complexity for efficient implementation.

We'll cover the following...

Solution

  • We don’t need to flip the balanced parentheses, so we remove them first. If all the balanced parentheses are removed, we’ll be left with the parentheses of the form )))((((.

  • Let’s name the total number of open parenthesis as OpenCount and the total number of closed parenthesis as CloseCount.

  • When OpenCount is even, then CloseCount ...
