Q1. Find leaf node of binary tree
Ans. 
To find leaf node of binary tree, traverse the tree and check if node has no children.
• Traverse the binary tree using depth-first search or breadth-first search

• Check if a node has no left or right child, then it is a leaf node

• Repeat the process for all nodes until all leaf nodes are found

Q2. How to get left view right view top view of binary tree
Ans. 
To get left view, right view, and top view of a binary tree, perform level order traversal and keep track of the first node encountered at each level.
• Perform level order traversal of the binary tree

• Keep track of the first node encountered at each level for left view

• Keep track of the last node encountered at each level for right view

• For top view, use a map to store horizontal distance and node pairs

Q1. What is Acceleration?
Ans. 
Acceleration is the rate of change of velocity of an object with respect to time.
• Acceleration is a vector quantity, meaning it has both magnitude and direction.

• It is measured in meters per second squared (m/s^2).

• Acceleration can be positive (speeding up), negative (slowing down), or zero (constant speed).

• Examples of acceleration include a car accelerating from a stop sign, a roller coaster going down a hill, and a rock

Q2. Rate of change of velocity.
Ans. 
Rate of change of velocity is known as acceleration.
• Acceleration is the derivative of velocity with respect to time.

• It is measured in meters per second squared (m/s^2).

• Positive acceleration means speeding up, negative acceleration means slowing down.

• Examples of acceleration include a car accelerating from a stop sign or a roller coaster going down a hill.
