DSA:

Question 1: Write a function to determine the height of a binary tree. The height is defined as the number of edges between the root and the furthest leaf.

Inputs:

• The root node of the binary tree.

Output:

• The height of the tree.

Example:

Binary Tree:
      3
     / \
    2   5
   /   / \
  1   4   6

Output: 2

Question 2: Implement a function to perform a level order traversal (breadth-first traversal) on a binary tree.

Inputs:

• The root node of the binary tree.

Output:

• The values of the nodes in level order.

Example:

Binary Tree:
      3
     / \
    9  20
       / \
      15  7

Output: [3, 9, 20, 15, 7]

WEB-DEV:

1. Create a React component called ButtonClicker that displays a button. When clicked, the button should change its text from "Click me" to "Clicked!".
2. Create a React component called LikeButton that displays a button labeled "Like". When clicked, it should increment a count displayed next to the button indicating how many times it's been clicked.
3. Create a React component called TrafficLight that displays a traffic light with three colors: Red, Yellow, and Green. Implement a button that toggles the state of the traffic light (Red -> Green -> Yellow -> Red).
