You play a game of [Go](https://www.wikiwand.com/en/Go_(game)). You are given a board with some stones placed on it (`w` is white stone, `b` is black stone, `e` is empty spot.), and you are given a new black stone to be placed on an empty spot. You have to return the number of enemy stones that this move will capture.\n\n**Example 1:**\n```\nInput: board = [[e, e, e, e, b, b, b], row = 2, col = 5\n\t\t\t    [e, e, e, e, b, w, b],\n\t\t\t    [e, e, e, e, b, e, b],\n\t\t\t    [e, e, e, e, e, e, e]]\n\nOutput: 1\nExplanation: If you place a black stone on (2, 5) then you capture 1 white stone from the enemy.\n```\n\n**Example 2:**\n```\nInput: board = [[e, e, e, e, b, b, b], row = 2, col = 5\n\t\t\t    [e, e, e, b, w, w, b],\n\t\t\t    [e, e, e, e, b, e, b],\n\t\t\t    [e, e, e, e, e, e, e]]\n\nOutput: 2\nExplanation: As u can see, 2 whites are enclosed.\n```\n\n**Example 3:**\n```\nInput: board = [[e, e, e, e, b, b, b], row = 2, col = 5\n\t\t\t    [e, e, e, e, w, w, b],\n\t\t\t    [e, e, e, e, b, e, b],\n\t\t\t    [e, e, e, e, e, e, e]]\n\nOutput: 0\nExplanation: Because the enclosure is not complete, white can escape from the left side.\n```\n\n**Example 4:**\n```\nInput: board = [[e, e, b, b, b, b, b], row = 2, col = 5\n\t\t\t    [e, e, b, w, e, w, b],\n\t\t\t    [e, e, b, b, b, e, b],\n\t\t\t    [e, e, e, e, e, e, e]]\n\nOutput: 0\nExplanation: This one does not qualify as an enclosure, it is an \'eventual enclosure\', meaning that the white regions still have scope for expansion.\n```
