true
false

1. suppose you have the following list of numbers to sort: 18, 10, 4, 2, 14, 8, 20, 7, 1, 13

which list represents the partially sorted list after three complete passes of insertion sort?
2, 4, 10, 18, 14, 8, 20, 7, 1, 13
4, 10, 18, 2, 14, 8, 20, 7, 1, 13
1, 2, 4, 7, 8, 10, 13, 14, 18, 20
10, 18, 4, 2, 14, 8, 20, 7, 1, 13

1. what will be displayed by the following code?

d = {\autumn\:50, \peter\:56}
print(list(d.keys()))
(\autumn\:50, \peter\:56)
(\autumn\, \peter\)
\autumn\:50, \peter\:56
\autumn\, \peter\

In Python, the def - block (the code block following the def statement) is executed when the function is called, not when the def statement itself is run.

Step1: Insertion sort first pass

The first element is considered sorted. For the second element (10), since 10 < 18, the list becomes [10, 18, 4, 2, 14, 8, 20, 7, 1, 13].

Step2: Insertion sort second pass

For the third element (4), it is inserted in the correct position among the first two sorted elements. The list becomes [4, 10, 18, 2, 14, 8, 20, 7, 1, 13].

Step3: Insertion sort third pass

For the fourth element (2), it is inserted in the correct position among the first three sorted elements. The list becomes [2, 4, 10, 18, 14, 8, 20, 7, 1, 13].

In Python, the keys() method of a dictionary returns a view object of the dictionary's keys. Wrapping it with list() converts this view object into a list of keys. For the dictionary d = {"autumn":50, "peter":56}, the keys are "autumn" and "peter", and the list of keys is ["autumn", "peter"].
