Fibonacci series can be generated in Informatica using a recursive function.
Create a mapping with a recursive function
Use a variable port to store the previous two values
Use an expression transformation to generate the series
Example: f(0) = 0, f(1) = 1, f(n) = f(n-1) + f(n-2)

Given a list of integer find the longest increase sequence
Find the first non-repeating integer in a list using Java 8 stream API.
Use Java 8 stream API to group integers by count
Filter out integers with count greater than 1
Return the first non-repeating integer
Using Java 8 Stream API to find the fruit with maximum price in a Map of fruits.
Use entrySet() method to get a stream of key-value pairs from the Map.
Use max() method with Comparator.comparing() to find the entry with maximum price.

Program to check if parenthesis are properly balanced
Use a stack data structure to keep track of opening parenthesis
Iterate through the input string and push opening parenthesis onto the stack
When a closing parenthesis is encountered, pop from the stack and check if it matches the corresponding opening parenthesis
If stack is empty at the end and all parenthesis are matched, then the input has properly balanced parenthe

The four pillars of OOP are encapsulation, inheritance, polymorphism, and abstraction.
Encapsulation: Bundling data and methods that operate on the data into a single unit.
Inheritance: Allows a class to inherit properties and behavior from another class.
Polymorphism: Ability to present the same interface for different data types.
Abstraction: Hides the complex implementation details and only shows the necessary features.
Print a specific pattern using loops
Use nested loops to print the desired pattern
Increment the number of characters printed in each row
Adjust the spacing to create the desired pattern
Static keyword is used in programming languages to declare variables, functions, or classes that are shared among all instances of a class or are only accessible within a specific scope.
Static variables retain their values between function calls
Static functions can only be called within the same file
Static classes cannot be instantiated and are used for grouping related methods and properties

Easy applitute question with 1 coding question at the end
String builder is faster but not thread-safe, while string buffer is slower but thread-safe.
String builder is recommended for single-threaded applications for better performance.
String buffer is recommended for multi-threaded applications to ensure thread safety.
Example: StringBuilder sb = new StringBuilder(); StringBuffer sbf = new StringBuffer();
The final keyword in OOP is used to restrict the user from changing the value of a variable, overriding a method, or inheriting from a class.
Final variable: value cannot be changed once assigned
Final method: cannot be overridden in child classes
Final class: cannot be inherited by other classes
BSF graph explanation
BFS (Breadth-First Search) is a graph traversal algorithm that explores all the neighbor nodes at the present depth before moving on to the nodes at the next depth.
It uses a queue data structure to keep track of the nodes to visit next.
BFS is often used to find the shortest path in an unweighted graph.
Example: BFS can be used to find the shortest path in a maze from the starting point to the exit.
