Help: 
The MOD operator returns the remainder
of a division:
e.g.
7 MOD 3 = 1

numbers = [3, 12, 7, 23, 14, 11, 12]
code = []

FOR i FROM 0 TO length(numbers)-2
    IF numbers[i+1] > numbers[i] THEN

FOR i FROM 2 TO 4

OUTPUT code

myList = [2,5,7,8,1,3,6,9,8]

In most high level programming languages, you can store a collection of values using either a list or an array.

e.g.
primeNumbers = [2, 3, 5, 7, 11, 13, 17, 19]

You can access any value of a list using a index to give the position of the value you would like to access. The first value of the list is at position 0.

e.g.
print(primeNumbers[0])
>>> Ouput 2

print(primeNumbers[1])
>>> Ouput 3

print(primeNumbers[2])
>>> Ouput 5

... and so on.

You can count how many items you have in a list using the length function:

e.g.
print(length(primeNumbers))
>>> Ouput 8

Hence you can easily access the last value of a list as follows:
print(primeNumbers[length(primeNumbers)-1])
>>> Ouput 19

You can create a 2D array (or a list of lists) as follows:
grid=[["X","X","O"],["O","X","O"],["X","O","O"]]

To access a value from this Noughts and Crosses grid, you will need to use two indices: one for the row number and one for the column.
e.g.
print(grid[0][0])
>>> Ouput X (top left corner of the grid)
