Count the Perfect Squares

A perfect square is a whole number you get by multiplying a whole number by itself: 0, 1, 4, 9, 16, 25, ...

Write count_perfect_squares(numbers) that returns how many numbers in the list are perfect squares.

Every number is a whole number, 0 or bigger.
0 counts (it's 0 × 0).
Duplicates each count separately.
An empty list gives 0.

Use math.sqrt and math.floor. math.floor rounds a number down to the whole number below it.

Examples

numbers = [1, 2, 4, 9, 10]

returns 3

numbers = [2, 3, 5]

returns 0
