As I’ve said before, the lord who used to live here, highly appreciated the solitude, therefore it’s not surprising that the estate was surrounded by a very high and thick stone wall. Fortunately, you’ve foreseen this and took some explosives with you (I don’t even want to know where you got it from). However, it’s unlikely that this modest reserve will suffice to blow up the wall just anywhere - it’d be better to act for sure and find the most vulnerable place.
As input you'll get a multiline string consists of '0' and '#' - a view of a stone wall from above. The '#' will show the stone part of the wall and the '0' will show the empty part. The relative location of you and the wall is as follows: you look at the array from the bottom of it.
Your task is to find the index of the place where the wall is the narrowest (as shown at the picture below). The width of the wall is the height of the columns of the array (multiline string). If there are several such places, return the index of leftmost. Index starts from 0.
Input: Array represents the stone wall.
Output: Index of leftmost of all weakest spots.
stone_wall(''' ########## ####0##0## 00##0###00 ''') == 4
How it is used: For the architecture analisys.
3x3 <= array size <= 10x10
