In this video, we dive deep into the Stacks – a powerful and efficient technique used to solve a variety of problems on arrays and strings

We'll cover:

When and why to use Stacks
Step-by-step examples with dry runs

Common problems like:

Where we can apply Stack
Monotonic stack
Valid Parenthesis
Next Greater Element
Simplify Path

Time Stamps :
00:00 - Intro
00:08 - Definitions, Where Stack is Applied
10:04 - 1.Valid Parenthesis
17:47 - 2.Next Greater Element (Monotonic Stack)
33:42 - 3.Simplify Path
