Consider the insertion sort algorithm, which sorts an array `A` of length `N` in ascending order. Below is a partial implementation of the insertion sort algorithm in Python: python function insertion_sort(A[O...N-1]) if N > 1: for i in range(1, N): index = i for j in range(i - 1, -1, -1): if A[index] < A[j]: A[index], A[j] = A[j], A[index] index = j else: break Copy code a. Complete the implementation of the 'insertion_sort function in Python, ensuring that it correctly sorts the input array `A` in ascending order. b. Explain the purpose of each loop and conditional statement within the insertion sort algorithm. c. Test your implementation with different input arrays and verify that it produces the expected output. d. Analyze the time complexity of your 'insertion_sort' implementation. Provide a step-by-step explanation of how you determined the time cplexity and discuss its implications.

Can you tell us more about the compiler and possible testing methods?

Before going on, let's have a look at the compiler's options and the testability advice.

What are the possible problems of test-first development?

How do you mean to use the word "constructors" in this context? For the life of me, I can't figure out what the point of Constructors is.

Let's start with an introduction to the compiler and then move on to some testability tips.

We'll go over the testability tip and provide a quick tour of the compiler in this class.

In this section, we'll introduce the compiler and go through the testability hint.

"White box testing" – what is it? Do white box tests really need to be performed?
