Task 1: Fill in the heading.

Open your cornell notes word document, if you would rather fill it in by hand then feel free to print it out. Fill in the video title and the topic at the top of the page. See example below.

Open a Cornell notes sheet by clicking on the image below.

Remember good notes allow students to help each other problem solve

Good notes will help you organise and process data and information

Cornell notes help you retain and recall information by having three different ways/sections where you process the information.

Note taking is a way of helping you to remember things you would otherwise forget. It also stimulates our critical thinking skills.

Remember! whenever you see the notes icon this means the information is important and you should write it down on your notes sheet.

Two- dimensional Arrays

A two-dimensional array is a data structure in computer science that stores a collection of items in a grid-like format, similar to a table in a spreadsheet. Imagine a grid of lockers, each locker is addressed by its row and column, and can store one item.

For example, in computer science, a two-dimensional array can be used to store a table of numbers or strings, where each element can be accessed by its row and column. They are useful when you need to organize information in a tabular format, like a table of scores or a map.

A chessboard example

Here's an example of how you could create a 2D array in Python that represents a chessboard, where the values in the array are strings representing the pieces on the chessboard:

chessboard = [ ["r", "n", "b", "q", "k", "b", "n", "r"], ["p", "p", "p", "p", "p", "p", "p", "p"], [" ", " ", " ", " ", " ", " ", " ", " "], [" ", " ", " ", " ", " ", " ", " ", " "], [" ", " ", " ", " ", " ", " ", " ", " "], [" ", " ", " ", " ", " ", " ", " ", " "], ["P", "P", "P", "P", "P", "P", "P", "P"], ["R", "N", "B", "Q", "K", "B", "N", "R"] ]

Here, the chessboard is represented as a list of lists, where each inner list represents a row on the chessboard, and the items in the list represent the pieces on the chessboard, with "r" representing a black rook, and "R" representing a white rook etc.

You can access an individual piece on the chessboard using two sets of square brackets, like this:

chessboard[i][j]

where i and j are the indices of the row and column of the piece you want to access. For example chessboard[0][0] would give you the piece on top left corner.

You can also use a nested for loop to iterate through all pieces on the chessboard, like this:

for row in chessboard: for piece in row: print(piece)

Use would print all the pieces of the chessboard in row major order.
