# Holes in Numbers

*holes*in them?

An interesting problem is to count such holes in a given number.

For example, the number \(68724\) and \(59013\) have \(3\) and \(2\) holes respectively.

Counting the *holes* in relatively small numbers are pretty easy, but how about finding the *holes* in a 500 digits number?

How many *holes* are there in the 500-digits number?

You can find the number here.
