Abstraction is the process of simplifying complex systems by focusing on essential details and hiding unnecessary complexities.
Abstraction allows us to create models or representations of real-world objects or systems in software.
It helps in managing complexity by breaking down a system into smaller, more manageable parts.

The statement to use for selecting based on integer inputs is the 'switch' statement.
The 'switch' statement allows for multiple cases to be evaluated based on the value of an integer input.
Each case represents a possible value of the input, and the corresponding code block is executed if the value matches.
The 'switch' statement also provides a 'default' case which is executed if none of the cases match the input value.

Joins in SQL are used to combine data from two or more tables based on a related column.
Inner join returns only the matching rows from both tables
Left join returns all rows from the left table and matching rows from the right table
Right join returns all rows from the right table and matching rows from the left table
Full outer join returns all rows from both tables, with NULL values for non-matching rows
Cross join retur
Given an array of integers, find a contiguous subarray with a given sum.
Use a sliding window approach to iterate through the array and keep track of the current sum.
If the current sum exceeds the given sum, move the window's left endpoint forward.
If the current sum is less than the given sum, move the window's right endpoint forward.
If the current sum equals the given sum, return the subarray.
Time complexity: O(n), Spa

Find the sum of the subarray with the maximum sum in a given array.
Iterate through the array and keep track of the current sum and maximum sum.
Update the maximum sum if the current sum becomes greater.
Handle cases where the array has all negative numbers or empty subarray.
Example: For input [-2, 1, -3, 4, -1], the maximum sum subarray is [4] with sum 4.
Given a positive integer N

A prime number is a natural number greater than 1 that has no po...
Identify all prime numbers less than or equal to a given positive integer N.
Iterate from 2 to N and check if each number is prime
Use the Sieve of Eratosthenes algorithm for efficient prime number identification
Optimize by only checking numbers up to square root of N for divisibility
Joins in databases are used to combine rows from two or more tables based on a related column between them.
Joins are used to retrieve data from multiple tables based on a related column.
Common types of joins include INNER JOIN, LEFT JOIN, RIGHT JOIN, and FULL JOIN.
