Write a function safe_divide(a, b, fallback=0) that returns a / b, unless b is 0, in which case it returns fallback instead of raising a ZeroDivisionError.

Examples

Example 1

Input

safe_divide(10, 2)

Output

5.0

Explanation

Normal division since b is not zero.

Example 2

Input

safe_divide(10, 0)

Output

Explanation
