Medium ⏱ 12 min 46% acceptance ★★★★☆ 4.3

Write a function magnitude(z) that takes a Python complex number z and returns its magnitude (absolute value), rounded to 2 decimal places. Recall a complex number has a .real and .imag part.

Examples

Example 1

Input

magnitude(3 + 4j)

Output

5.0

Explanation

sqrt(3^2 + 4^2) = 5.

Example 2

Input

magnitude(1 + 1j)

Output

1.41

Explanation

sqrt(2) rounded to 2 decimals.

Constraints

`z` is always a valid Python complex number.
