Servant Leaders: Prioritize the needs of others, empowering them to achieve their goals
Authentic Leaders: Lead with integrity, honesty, and transparency

Autocratic: Centralized decision-making, little input from others
Democratic: Collaborative decision-making, high input from others
Laissez-Faire: Minimal supervision, high autonomy for employees
Situational: Leadership style adapts to the situation and individuals involved

Trait Theory: Leaders are born with certain traits that make them successful
Behavioral Theory: Leaders can be made through learning and development
Contingency Theory: Leadership style is dependent on the situation and environment
Path-Goal Theory: Leaders motivate and direct employees to achieve goals

Communication: Effective communication is critical for leadership success
Motivation: Ability to inspire and motivate individuals to achieve their goals
Decision-Making: Ability to make informed, timely, and effective decisions
Emotional Intelligence: Ability to understand and manage one's own emotions and those of others

Change Management: Leading individuals through times of change and uncertainty
Stakeholder Management: Managing the expectations and needs of various stakeholders
Cultural Diversity: Leading a diverse workforce with varying cultural backgrounds
Ethical Leadership: Making ethical decisions that align with the organization's values and principles

There are four types of leaders:
- Transactional Leaders: focus on exchanging rewards for desired behavior and performance
- Transformational Leaders: inspire and motivate individuals to achieve a shared vision
- Servant Leaders: prioritize the needs of others, empowering them to achieve their goals
- Authentic Leaders: lead with integrity, honesty, and transparency

There are four main leadership styles:
- Autocratic: centralized decision-making, little input from others
- Democratic: collaborative decision-making, high input from others
- Laissez-Faire: minimal supervision, high autonomy for employees
- Situational: leadership style adapts to the situation and individuals involved

There are four main leadership theories:
- Trait Theory: leaders are born with certain traits that make them successful
- Behavioral Theory: leaders can be made through learning and development
- Contingency Theory: leadership style is dependent on the situation and environment
- Path-Goal Theory: leaders motivate and direct employees to achieve goals

Effective communication is critical for leadership success
Ability to motivate individuals to achieve their goals
Ability to make informed, timely, and effective decisions
Ability to understand and manage one's own emotions and those of others (Emotional Intelligence)

Leading individuals through times of change and uncertainty (Change Management)
Managing the expectations and needs of various stakeholders (Stakeholder Management)
Leading a diverse workforce with varying cultural backgrounds (Cultural Diversity)
Making ethical decisions that align with the organization's values and principles (Ethical Leadership)

A tree is a hierarchical data structure consisting of nodes, where each node has a value and zero or more child nodes.
The root node is the topmost node in the tree.
Child nodes are nodes that are directly below a parent node.
A parent node is a node that has child nodes.
Sibling nodes are nodes that share the same parent node.
Leaf nodes are nodes with no child nodes.
The height of a tree is the number of edges between the root node and the furthest leaf node.
The depth of a node is the number of edges between a node and the root node.

A binary tree is a tree where each node has at most two child nodes (left and right).
A B-tree is a self-balancing search tree that keeps data sorted and allows search, insert, and delete operations in logarithmic time.

Inorder traversal visits nodes in the order: Left subtree -> Root -> Right subtree.
Preorder traversal visits nodes in the order: Root -> Left subtree -> Right subtree.
Postorder traversal visits nodes in the order: Left subtree -> Right subtree -> Root.

A stack is a linear data structure that follows the Last-In-First-Out (LIFO) principle, where elements are added and removed from the top of the stack.
The push operation adds an element to the top of the stack.
The pop operation removes the top element from the stack.
The peek operation returns the top element without removing it.
The top of the stack is the most recently added element.
The bottom of the stack is the first element added to the stack.
A stack is empty when it has no elements.

Stacks can be used to evaluate postfix expressions by parsing the operators and operands.
Stacks can be used to implement recursive algorithms iteratively.
Stacks can be used to parse syntax in compilers and interpreters.
