Use arrays to store collections of data, e.g., String[] names = {"Alice", "Bob", "Charlie"};
Manipulate arrays with loops, e.g., for (String name : names) { System.out.println(name); }
Utilize objects to represent complex data, e.g., class Person { String name; int age; }
Implement methods to operate on arrays and objects, e.g., a m...

A higher order function is a function that can take other functions as parameters or return functions as results.
Higher order functions can be used to create more flexible and reusable code.
They can be used to implement callbacks, event handling, and functional programming concepts.
Example: map, filter, and reduce functions in JavaScript are higher order functions.
Fragments are modular sections of an activity's user interface, allowing for more flexible and dynamic UI designs.
Fragments can be reused across multiple activities
They help in creating responsive UIs for different screen sizes
Fragments can be added or removed dynamically during runtime
They are useful for implementing multi-pane layouts on tablets
Memoization techniques involve storing the results of expensive function calls and returning the cached result when the same inputs occur again.
Using a hash table to store previously computed results
Implementing memoization with dynamic programming
Memoizing recursive functions to avoid redundant calculations

Immutable types provide safety...
