Print numbers in a tree format
Use recursion to print numbers in a tree structure
Start with the root node and recursively print child nodes
Use indentation to represent levels in the tree
Example: 1 --2 ----3 --4
Join queries are used to combine data from multiple tables based on a related column between them.
Use JOIN keyword to combine tables based on a common column
Specify the columns to select from each table
Use WHERE clause to specify the join condition
A linked list is a data structure that consists of a sequence of nodes, each containing a reference to the next node.
Each node has a data field and a next field that points to the next node
Insertion and deletion can be done efficiently
Traversal starts from the head node and continues until the end node is reached
This code demonstrates a simple Python function to calculate the factorial of a number using recursion.
Define a function named 'factorial' that takes one argument 'n'.
Check if 'n' is less than or equal to 1; if so, return 1.
Otherwise, return 'n' multiplied by 'factorial(n-1)'.
Example: factorial(5) returns 120.
Calculate the angle between the hour and minute hands of a clock at 3:15.
Each hour on the clock represents 30 degrees (360 degrees / 12 hours).
Each minute represents 6 degrees (360 degrees / 60 minutes).
At 3:15, the hour hand is at 97.5 degrees (3 hours * 30 + 15 minutes * 0.5).
The minute hand is at 90 degrees (15 minutes * 6).
The angle between the hands is the absolute difference: |97.5 - 90| = 7.5 degrees.
Factorial of a number can be calculated using both iterative and recursive methods.
Iterative method involves using a loop to multiply numbers from 1 to n.
Recursive method involves calling the function with n-1 until n reaches 1.
Example: Factorial of 5 using iterative method: 5! = 5*4*3*2*1 = 120
Example: Factorial of 5 using recursive method: 5! = 5 * 4!
Example: Factorial of 4 using recursive method: 4! = 4 * 3!

- Ans.
A self join query is used to join a table to itself in a SQL query.
Self join is used when a table needs to be joined with itself to compare rows within the same table.
It requires aliasing the table with different names to distinguish between the two instances of the same table.
Commonly used in hierarchical data structures or when comparing related rows in a table.
- Q2. Group by query per catagory
- Ans.
Group by query is used to group data based on a specific category.
Use the GROUP BY clause in SQL to group data based on a specific column
Aggregate functions like COUNT, SUM, AVG can be used with GROUP BY to perform calculations on grouped data
Example: SELECT category, COUNT(*) FROM products GROUP BY category
