Implement stack data structure
Use an array or linked list to store elements
Push operation adds element to top of stack
Pop operation removes element from top of stack
Peek operation returns top element without removing it
Global variables are accessible from any part of the program and can be modified by any function.
Global variables are declared outside of any function.
They can be accessed and modified by any function in the program.
If a function modifies the value of a global variable, the new value is visible to all other functions.
Global variables can be useful for sharing data between functions.
However, overuse of global variables
Program to transpose a matrix
Iterate through rows and columns of the matrix
Swap the elements at (i,j) and (j,i) positions
Return the transposed matrix
Pre and post fix operators are used to increment or decrement a value before or after it is used in an expression.
Pre-fix operator (++x) increments the value of x and returns the new value.
Post-fix operator (x++) returns the value of x and then increments it.
Both operators can be used with variables of numeric data types.
They can also be used with pointers to increment or decrement the memory address they point to.

Microservices offer benefits such as scalability, flexibility, and easier maintenance.
Scalability: Microservices can be scaled independently, allowing for better resource utilization.
Flexibility: Microservices can be developed and deployed independently, allowing for faster iteration and innovation.
Easier maintenance: Microservices are smaller and more focused, making it easier to identify and fix issues.

Spring Data JPA simplifies the implementation of data access layer in Spring applications.
Provides a framework for easily creating repositories and queries
Reduces boilerplate code for data access layer
Supports pagination and sorting of data
Integrates with Spring's transaction management
Example: @Repository interface UserRepository extends JpaRepository
A hash map is a data structure that uses a hash function to map keys to values in constant time.
Hash map uses an array to store key-value pairs
The hash function is used to convert the key into an index of the array
Collisions occur when two keys map to the same index, which is resolved using chaining or open addressing
Retrieving a value from a hash map involves computing the hash of the key and then looking up the corre...
Comparable is an interface used for natural ordering while Comparator is an interface used for custom ordering.
Comparable is implemented by the class itself while Comparator is implemented by a separate class.
Comparable provides a single method compareTo() while Comparator provides a single method compare().
Comparable is used for sorting elements in a collection while Comparator is used for custom sorting.
Example: Stri...
Concurrent Hash Map is a thread-safe implementation of a hash map.
It allows multiple threads to access and modify the map concurrently.
It uses a technique called lock striping to achieve high concurrency.
It is part of the java.util.concurrent package in Java.
Example: ConcurrentHashMap in Java.
