Write me some pseudocode for one pass of the SelectionSort algorithm through random values stored in an Unordered-List, or Linked-List, of values (rather than a standard "Python" List).

How would you implement a swap using a Linked-List?

What is the minimum number of variables required?

Step me through an illustrated example (including all needed variables/arrows) of a Linked-List of size 5, where the positions of nodes 3 and 4 are swapped.

Show the pseudocode to accomplish this in your report

The Algorithm for selection sort is given below:

1) If Linked list is empty then make the node as

  head and return it.

2) If the value of the node to be inserted is smaller  

  than the value of the head node, then insert the node  

at the start and make it head.

3) In a loop, find the appropriate node after  

  which the input node  is to be inserted.  

  To find the appropriate node start from the head,  

  keep moving until you reach a node who's value is greater than  

  the input node. The node just before given node is the

appropriate .

4) Insert the node  after the appropriate node

 found in step 3

Swap can be implemented using LInked-List by multiple assignment as shown.

The minimum number of variables required is 2.

An example is given below

your_list = ["a", "b", "c", "d", "e"]

your_list[3], your_list[4] = your_list[4], your_list[3]

print(your_list)

OUTPUT

['a', 'b', 'd', 'c', 'e']
