Find the contiguous subarray with the largest sum in an integer array using an efficient algorithm.
Kadane's Algorithm: This algorithm efficiently finds the maximum sum subarray in O(n) time by maintaining a running sum.
Initialization: Start with two variables, maxSum and currentSum, initialized to the first element of the array.
Iterate through the array: For each element, update currentSum to be the maximum of the...
Reverse a string by iterating through the characters and swapping them

Create a dictionary using two lists
Use zip() function to combine two lists into key-value pairs
Use dict() function to convert the key-value pairs into a dictionary
Call by reference is a method of passing arguments to a function where the actual memory address of the variable is passed.
In call by reference, the function receives a reference to the original variable, allowing it to modify the value of the variable directly.
Changes made to the parameter inside the function will affect the original variable outside the function.
Example: void swap(int &a, int &b) { int temp = a;...

Static variables are shared among all instances of a class, while non-static variables are unique to each instance.
Static variables are declared using the 'static' keyword and retain their value throughout the program's execution.
Non-static variables are declared without the 'static' keyword and have separate values for each instance of a class.
Static variables are accessed using the class name, while non-static v...

Comparable is an interface used for natural ordering, while Comparator is an interface used for custom ordering in Java.
Comparable interface is used to define the natural ordering of objects. It is implemented by the class whose objects are to be compared.

Encapsulation is the concept of bundling data and methods that operate on the data into a single unit, known as a class.
Encapsulation helps in hiding the internal state of an object and restricting access to it.
It allows for data hiding, which prevents outside code from directly accessing an object's internal state.
Encapsulation also helps in achieving data abstraction, where the internal details of an object are ...
Page life cycle refers to the series of events that occur from the time a page is requested to the time the page is fully rendered and sent to the client.
Page request is made by the client
Page is initialized, controls are created and properties are set
Page is loaded and controls are populated with data
Page is rendered and sent to the client

The == operator checks for equality of values, while the equals() method checks for equality of objects.
The == operator compares the values of two objects, while the equals() method compares the objects themselves.
The == operator is used for primitive data types, while the equals() method is used for objects.
Example: int a = 5; int b = 5; a == b will return true, but a.equals(b) will not work as int is a primitive data...
Dependency inversion is a design principle where high-level modules should not depend on low-level modules, but both should depend on abstractions.
High-level modules should not depend on low-level modules, both should depend on abstractions
Abstractions should not depend on details, details should depend on abstractions
Inversion of control containers like Spring Framework in Java implement dependency inversion
ACID is a set of properties that guarantee database transactions are processed reliably.
ACID stands for Atomicity, Consistency, Isolation, Durability
Atomicity ensures that all operations in a transaction are completed successfully or none at all
Consistency ensures that the database remains in a valid state before and after the transaction
Isolation ensures that multiple transactions can occur concurrently without affect...
Isolation levels in databases determine how transactions interact with each other.
Isolation levels define the degree to which one transaction must be isolated from the effects of other transactions.
Common isolation levels include READ UNCOMMITTED, READ COMMITTED, REPEATABLE READ, and SERIALIZABLE.
Higher isolation levels provide more data consistency but may impact performance.
For example, in READ COMMITTED isolation le...

HashMap is a data structure that stores key-value pairs and uses hashing to efficiently retrieve values.
HashMap uses an array of buckets to store key-value pairs.
When a key-value pair is added, the key is hashed to determine the index in the array where it will be stored.
If multiple keys hash to the same index (collision), a linked list or tree is used to store multiple entries at that index.
To retrieve a value, the ke...
