Adaboost is a machine learning algorithm that combines multiple weak learners to create a strong learner.
Adaboost stands for Adaptive Boosting.
It works by adjusting the weights of incorrectly classified instances so that subsequent weak learners focus more on them.
The final prediction is made by combining the predictions of all the weak learners, weighted by their accuracy.
Example: Adaboost is commonly used in face det

Decision tree is a predictive modeling tool that uses a tree-like graph of decisions and their possible consequences.
Decision tree splits data into subsets based on the value of a certain attribute
It recursively divides data into smaller subsets until a stopping criterion is met
Each internal node represents a decision based on an attribute, and each leaf node represents the outcome
Pressure generally increases with temperature due to the kinetic energy of gas molecules.
Pressure is directly proportional to temperature in a closed system (Boyle's Law).
As temperature increases, gas molecules move faster and collide with the container walls more frequently, increasing pressure.
For example, a balloon inflated indoors may burst when taken outside on a hot day due to increased pressure from higher tempe

Use bitwise operations to find the sum of two numbers without using mathematical operators.
Use bitwise XOR to find the sum of two numbers without carrying.
Use bitwise AND and left shift to find the carry.
Repeat the process until there is no carry left.
To delete a node from a linked list when only given a reference to the node, we can copy the data of the next node to the given node and delete the next node.
Copy the data of the next node to the given node
Update the next pointer of the given node to skip the next node
Delete the next node
I was interviewed in Nov 2016.
Need more context. What needs to be done with the large rectangle?
What are the dimensions of the rectangle?
Is it a 2D or 3D object?
What is the context of the problem?
Are there any constraints or limitations?
What tools or programming languages can be used?
Derive a formula to determine how many smaller rectangles fit into a bigger rectangle given their dimensions.
Calculate the number of times the smaller rectangle can fit into the bigger rectangle horizontally and vertically
Divide the width of the bigger rectangle by the width of the smaller rectangle to get the horizontal count
Divide the height of the bigger rectangle by the height of the smaller rectangle to get the ve...
At least 4 points are required to draw a rectangle.
A rectangle has 4 sides and 4 corners, so at least 4 points are needed to define those corners.
The points must be arranged in a specific order to form a closed shape with 4 sides.
Additional points can be used to add details or modify the shape of the rectangle.
The number of points required may vary depending on the software or tool used to draw the rectangle.
Answering how to calculate new coordinates of a scaled rectangle and providing a program for it.
To calculate new coordinates, multiply the original coordinates by the scaling factor
Scaling factor can be calculated by dividing the new length/breadth by the original length/breadth
Program can take input of original coordinates, scaling factor, and output new coordinates
Example: Original coordinates: (0,0), (0,5), (5,5), (...
I applied via Campus Placement
The question asks to fill the blanks in a pyramid where each number is the sum of the numbers in the bottom two cells.
Start from the bottom row and work your way up, calculating the sum of the numbers in the bottom two cells for each blank space.
Use a loop to iterate through each row and column of the pyramid.
Store the calculated sum in the corresponding blank space.
Repeat the process until all the blanks are filled.
Moore's Law is the observation that the number of transistors in a dense integrated circuit doubles about every two years.
Named after Intel co-founder Gordon Moore
First stated in 1965
Has been a driving force behind technological advancements
Predicts exponential growth in computing power
Has been challenged in recent years due to physical limitations
A process is an instance of a program while a thread is a subset of a process.
A process has its own memory space while threads share memory space

Explain Big O notation
Big O notation is used to describe the time complexity of an algorithm
It helps us understand how the algorithm's performance changes with input size
O(1) means constant time, O(n) means linear time, O(n^2) means quadratic time
We want algorithms with lower Big O values for better performance
