Balanced Parentheses Problem: Swift Stack Implementation

Learn how to solve the classic "Balanced Braces" (Valid Parentheses) interview problem in Swift using a Stack data structure. In this tutorial, we break down the logic step-by-step: • Tracking opening braces using a Stack (LIFO) • Matching pairs efficiently with Tuples, Sets, and Dictionaries for O(1) lookups • Validating nested brackets across edge cases Timestamps: 0:00 - Problem Overview & Intuition 0:26 - Algorithm & Stack Logic 1:30 - Visual Walkthrough with Examples 2:50 - Swift Code Implementation 5:05 - Verifying Balanced vs. Unbalanced Cases #Swift #iOSDev #DataStructures #Algorithms #CodingInterview #SwiftLang
