A square of squares
You like building blocks. You especially like building blocks that are squares. And what you even like more, is to arrange them into a square of square building blocks!
However, sometimes, you can’t arrange them into a square. Instead, you end up with an ordinary rectangle! Those blasted things! If you just had a way to know, whether you’re currently working in vain… Wait! That’s it! You just have to check if your number of building blocks is a perfect square.
Task
Given an integral number, determine if it’s a square number:
In mathematics, a square number or perfect square is an integer that is the square of an integer; in other words, it is the product of some integer with itself.
The tests will always use some integral number, so don’t worry about that in dynamic typed languages.
Examples
isSquare(-1) returns false
isSquare(0) returns true
isSquare(3) returns false
isSquare(4) returns true
isSquare(25) returns true
isSquare(26) returns false
Solution :
def is_square(n):
if n < 0:
return False
elif n == 0:
return True
i = 1
while i < n:
m = i * i
if m == n:
return True
elif m > n:
return False
i += 1
return False # fix me
