Valid Parentheses 🔥 The Stack Trick Every Coding Interview Uses This is one of the most asked coding interview questions. Given a string containing (), {}, [], you must determine if the parentheses are valid and correctly ordered. The trick interviewers expect is using a Stack. ✔ Push opening brackets ✔ When you see a closing bracket, check the top of the stack ✔ If it matches → pop it ✔ If not → invalid If the stack is empty at the end → the string is valid. ⏱ Time Complexity: O(n) 📦 Space Complexity: O(n) This problem teaches a fundamental stack pattern used in many coding interviews. 📌 Save this reel for your DSA preparation 💬 Comment “STACK” if you want more stack interview problems. #leetcode #datastructures #codinginterview #algorithms #python

LeetCode 20. Valid Parentheses Given a string s containing just the characters '(', ')', '{', '}', '[' and ']', determine if the input string is valid. An input string is valid if: Open brackets must be closed by the same type of brackets. Open brackets must be closed in the correct order. Every close bracket has a corresponding open bracket of the same type. . Time Complexity = O(n), where 'n' is the number of characters Space Complexity = O(n), where 'n' is the number of characters .

Valid Parentheses | Stack DSA Interview Question Balanced Brackets using Stack – O(N) Optimized Solution This problem looks easy… but it’s a classic coding interview trap 😈 Counting brackets won’t work — order matters, and that’s where stack data structure comes in. Clean O(N) interview-ready logic 💡 Be a dhurandar — use data structures, not jugaad. If you’re preparing for DSA, LeetCode, or software engineering interviews, this is a must-know stack problem. 👉 Comment CODE for the implementation 👉 Follow for daily DSA & interview prep content 🚀 #DataStructures #engineeringstudents #coding #tech #stack

Stack isn’t just another DSA topic — it’s actually a whole interview pattern that shows up again and again. Some important stack patterns to know: • Monotonic Stack – Next Greater/Smaller Element, Stock Span, Largest Histogram • Expression Evaluation – Decode String, Basic Calculator • Stack Simulation – Asteroid Collision, Backspace String Compare • Parenthesis Problems – Valid Parentheses, Minimum Add/Remove • Stack using Two Queues – Important implementation concept If you get comfortable with these patterns, many interview problems become much easier to approach.
