Check if brackets in your code are perfectly balanced!

🎯 Problem: Validate Brackets

Hi! I'm Teju 👋 In a code editor, we need to check if all brackets are properly opened and closed.

Valid: {[()]} → true
Invalid: {[(])} → false

Supported brackets: { } [ ] ( )

Rules: Every opening bracket must have a matching closing bracket in correct order.

⚙️ Algorithm: Stack-Based Validation

We use a stack to track opening brackets.

When we see a closing bracket, we check if it matches the most recent opening one.

  1. For each character:
    • If opening ({[ → PUSH to stack
    • If closing )]} → Check top of stack
      • If empty or doesn't match → false
      • Else → POP
  2. At end: Stack must be empty → true
