Get Free Wi-Fi Anywhere You Go

A new 'hacky' phone is launched, which has the feature of connecting to any Wi-Fi network from any distance away, as long as there aren't any obstructions between the hotspot and the phone. Given a string, return how many Wi-Fi hotspots I'm able to connect to.

• The phone is represented as a P.
• A hotspot is represented as an *.
• An obstruction is represented as a #. You cannot access a hotspot if they are behind one of these obstructions.

Examples

nonstopHotspot("*   P  *   *") ➞ 3

nonstopHotspot("*  * #  * P # * #") ➞ 1

nonstopHotspot("***#P#***") ➞ 0

Notes

• There will be only one phone.
• No other characters, other than spaces, will appear in the tests.
