Data Definition Language (DDL) is a set of commands used to define and manage the structure of database objects.
DDL is used to create, modify, and delete database objects such as tables, indexes, and views.
Common DDL commands include CREATE, ALTER, and DROP.
DDL statements do not manipulate data within the database, they only define the structure of the database objects.
Examples of DDL commands: CREATE TABLE, ALTER TABL
An orchestration tool is a software that automates and coordinates complex workflows and tasks in a system.
Orchestration tools help in managing and scheduling tasks across multiple systems or components.
They ensure that tasks are executed in the correct order and dependencies are met.
Examples of orchestration tools include Apache Airflow, Kubernetes, and Apache NiFi.
Data engineering processes involve collecting, storing, processing, and analyzing data to drive insights and decision-making.
Data collection: Gathering data from various sources such as databases, APIs, and sensors.
Data storage: Storing data in databases, data lakes, or data warehouses for easy access and retrieval.
Data processing: Cleaning, transforming, and aggregating data to make it usable for analysis.

Pointers are variables that store memory addresses of other variables in programming languages.
Pointers allow direct access and manipulation of memory locations.
They are commonly used in programming languages like C and C++.
Pointers can be used to pass variables by reference, allowing modifications to the original value.
They can also be used to dynamically allocate memory.
Example: int* ptr; // declares a pointer to an

Yes, I know C language. Here's a program to print numbers from 1 to 10 excluding 5.
Use a loop to iterate from 1 to 10
Inside the loop, check if the current number is equal to 5
If it is not equal to 5, print the number
The question was about finding the average of a set of numbers.
I approached the problem by first summing all the numbers in the set.
Then, I divided the sum by the total number of elements in the set to find the average.
I used a loop to iterate through the set and keep track of the sum and count of elements.
I was interviewed in Oct 2016.

Boundary traversal of a tree is the process of visiting the nodes on the boundary of a tree in a specific order.
The boundary traversal can be done in three steps: left boundary, leaf nodes, and right boundary.
For the left boundary, start from the root and traverse down the left side of the tree until reaching a leaf node.
For the leaf nodes, perform an inorder traversal to visit all the leaf nodes of the tree.
For the ri...
Find the nearest greater value of a given value in a Binary Search Tree (BST).
Start from the root node and compare the given value with the current node's value.
If the given value is less than the current node's value, move to the left subtree.
If the given value is greater than the current node's value, move to the right subtree.
Keep track of the closest greater value encountered while traversing the tree.

Given an infinite staircase with a broken kth step, find the maximum height we can reach in n rounds of jumping i steps.
We can start by jumping the maximum number of steps in each round until we reach the broken step.
After reaching the broken step, we can discard the i steps that would land us on the broken step and jump the remaining steps.
We can continue this pattern until we reach the maximum height we can reach wit
