Master Stack Patterns | DSA for Interviews

Stacks are not about memorizing push and pop operations. Stacks are about understanding patterns. In this video, I explain the Stack Data Structure in a pattern-based way, exactly how stack problems appear in coding interviews and real problem-solving scenarios. Instead of solving random questions, we focus on: 1- how stack problems are framed 2- how to identify the correct stack pattern 3- why stack naturally fits certain problems Patterns covered in this video: 1- Basic stack operations (push, pop, peek) 2- Next greater / next smaller element pattern 3- Monotonic stack pattern 4- Stack for expression evaluation 5- Stack for recursion simulation 6- Stack in string and array problems Each pattern is explained with: clear intuition problem structure common interview examples Who this video is for: beginners who struggle with stack problems students preparing for coding interviews anyone who wants to think logically instead of memorizing code Interview insight: If a problem involves: reversing order last seen element nearest greater or smaller element matching brackets Stack should immediately come to mind. Practice pattern-wise: I’ve shared my DSA sheet where stack questions are grouped pattern-wise, not randomly.
