# Zeros
## Task
Implement function `zeros(str)`, that for given expression will return the number of zeros in the end of number.
Expression contains only factorials of numbers and multiplying signs, like: `zeros('5!*7!*6!!*7!!')`
`5! === 1 * 2 * 3 * 4 * 5`
`10!! === 2 * 4 * 6 * 8 * 10`
`7!! === 1 * 3 * 5 * 7`
```js
zeros('5!') // -> 1 because 5! === 120
zeros('10!') // -> 2 because 10! === 3628800
zeros('9!!*10!!') // 2 -> because 9!!*10!! === 3628800
```
