Mastering Binary Trees, Searching, and Sorting Algorithms
Understanding Trees and Hierarchical Data
Trees can feel like a big jump from linear data structures like arrays or linked lists, but they are incredibly intuitive once you see how they organize data hierarchically. Here is a clear, scannable breakdown of the core concepts, representations, traversals, and Binary Search Tree (BST) operations you need to know.
1. Definitions and Core Concepts

1. What is a Stack?
A stack is a linear data structure that follows the LIFO (Last In, First Out) principle. Think of it like a stack of plates in a cafeteria: the last plate you place on top is the first one you take off.
2. Representation of a Stack
There are two primary ways to implement a stack in memory:
A. Array Representation (Static Allocation)
- How it works: A fixed-size array is allocated, and a variable named
topkeeps track of the index of the topmost element. - Initial State:

Mastering Blue Ocean Strategy and Strategic Roadmapping
Blue Ocean Strategy and Market Creation
Blue Ocean Strategy focuses on creating new market space rather than competing directly in existing market space. A red ocean is a crowded competitive environment where firms fight over existing demand. A blue ocean seeks to make competition less relevant by creating a new value proposition.
Blue Ocean Strategy is supported by practical tools:
- Strategy Canvas
- Four Actions Framework
- ERRC Grid
- Six Paths Framework
Together, they diagnose current market logic and help
