3. A two-dimensional array has been defined to hold the quantity of each of 5 different healthy
snack products sold in a tuckshop during the past three months.
The array is declared as follows:
sales = [[0, 0, 0, 0, 0],
[0, 0, 0, 0, 0],
[0, 0, 0, 0, 0] ]
Indexing of the array starts at 0, so the sales of the first product in the second month is held
in sales[1][0].
(a) Write a statement to assign the value 13 to the fifth product in the third month.
