Answer:

We will use the following approach to solve the problem:

Explanation:

1. We will identify the largest pancake in the given stack of pancakes, then insert the spatula below that pancake and flip the entire stack consisting of that largest identified pancake and all other pancakes on the top of it. Now the largest pancake will be on the top of the stack. Now insert the spatula at the bottom of stack and flip. In this way the largest pancake will become the bottommost pancake.

Now identify the next second largest pancake and repeat above process, keep on relating that until all are sorted.

This requires almost 2n-3 flips in worst case. ( For n pancakes). So the time complexity is O(n)

2n because one flip is required to bring pancake at top, then in 2nd flip it goes to bottom.

-3 because, the stack becomes sorted once the 2nd last pancake comes to the top. So next three steps are never required.

B) we want to find stack of n pancakes, that take omega (n) steps.

For that to happen, in worst case ( 2n-3 )>= cn , taking c=1

2n-3 >= n , => n >=3

So for n greater than or equal to 3 the condition holds.

Lists are used in Python to hold multiple values in one variable

(a) Nested list

A nested list is simply a list of list; i.e. a list that contains another list.

It is also called a 2 dimensional list.

An example is:

nested_list = [[ 1, 2, 3, 4]  , [ 5, 6, 7]]

(b) The “*” operator

The "*" operator is used to calculate the product of numerical values.

An example is:

num1 = num2 * num3

List slices

This is used to get some parts of a list; it is done using the ":" sign

Take for instance, you want to get the elements from the 3rd to the 5th index of a list

An example is:

firstList = [1, 2 ,3, 4, 5, 6, 7]

secondList = firstList[2:5]

The “+=” operator

This is used to add and assign values to variables

An example is:

num1 = 5

num2 = 3

num2 += num1

A list filter

This is used to return some elements of a list based on certain condition called filter.

An example that prints the even elements of a list is:

firstList = [1, 2 ,3, 4, 5, 6, 7]

print(list(filter(lambda x: x % 2 == 0, firstList)))

A valid but wrong list operation

The following operation is to return a single list, but instead it returns as many lists as possible

def oneList(x, myList=[]):

   myList.append(x)

   print(myList)

oneList(3)

oneList(4)
