Hello class!

Today ill choose the main two sorting algorithms in the background materials to answer the first question.

Lets discuss how Selection and Quicksort work!

Selection Sort:

In its simplest form, a selection sort algorithm sorts the data by  searching through a list for the smallest element then placing this in  the first index position. Once this is complete, it then repeats itself  moving up in elements until the whole list has been sorted. As others  have noted, the time complexity for this algorithm is O(n2).  Having a time complexity of O(n2) makes it a potentially very slow algorithm, especially if the data set is large (James, 2015).

Quicksort time!

Quicksort will sort an array by dividing it into two parts, it uses a  pivot element to compare and divide the array into higher/lower indexes  of the pivot value. Quicksort is implemented in a recursive manner  until the whole array is sorted. Typically in ascending order. The worst  case performance scenario O(n2), the same as selection sort, but on average will perform at O(n log n) (James,2015).


Graphs are nonlinear data structures that consist of a set number of nodes(vertices) and a set of edges that connect the nodes.

In graphs, a pair (x,y) is called an edge. an edge tells us that the x node connects to the y node.

When viewing a graph, the dots are the vertecies/nodes and the lines are the edges.

When it comes to questions that graphs can solve.

Anything with connected nodes is by definition a part of the graph  theory domain. Any tree or network and more. Social networks, semantic  networks, dependency trees, etc.

These can be used to map out chains of events, and connections. This  can be used to also find the shortest possible route between nodes as  well as determine root causes of issues within  routes/chains/relationships.
