Explanation

A constructor is automatically called when an object is instantiated, setting initial values.

Unlike regular methods, it has the same name as the class and does not have a return type.

Explanation

In a nested for-loop, the inner loop executes N times for each iteration of the outer loop.

This results in a total of N × N = N² iterations, making the time complexity O(N²).

Explanation

1. The list comprehension iterates through a, checks if num is even (num % 2 == 0), and if true, multiplies num by 2.
2. For the list a = [1, 2, 3, 4], the even numbers are 2 and 4. Multiplying them by 2 gives 4 and 8.

Output: [4, 8]
