1. The given code demonstrates functional programming. Here's a breakdown of what it does:- `numbers = [1, 2, 3, 4]`: This line creates a list called `numbers` containing four elements: 1, 2, 3, and 4.- `(mapilambda nin :- numbers)`: This line seems to be a typo. It should be `map(lambda n: n, numbers)`. The `map` function applies a given function to each element of an iterable (in this case, the `numbers` list) and returns a new iterable with the results. Here, the function is `lambda n: n`, which simply returns the input value `n`. So, this line creates a new list with the same elements as the `numbers` list.- `print(equaren)`: This line seems to be a typo. It should be `print(numbers)`. This line prints the `numbers` list.2. The Java code provided demonstrates the use of abstraction and inheritance, which are concepts commonly found in object-oriented programming (OOP) paradigms. In this code, we have an abstract class `Shape` with an abstract method `draw()`. This means that any subclass of `Shape` must provide an implementation for the `draw()` method. The `TestShapes` class is a test class that creates instances of `Circle` and `Square` classes (which are subclasses of `Shape`) and calls their `draw()` methods. This demonstrates the use of inheritance, where the `Circle` and `Square` classes inherit properties and methods from the `Shape` class.3. The given Python code aligns more with the functional programming paradigm. Here's why:- The code uses list comprehension, which is a functional programming construct for creating lists. It applies a simple operation (multiplication by 2) to each element of the `numbers` list using a lambda function.- There is no modification of the original `numbers` list. Instead, a new list `doubled` is created with the doubled values.In contrast, imperative programming typically involves modifying the state of variables directly, often using loops and assignments. Since the Python code does not modify the original list and uses a functional construct (list comprehension), it aligns more with functional programming.
