Problem Description The GeoSurvComp geologic survey company is responsible for detecting underground oil deposits. GeoSurvComp地質調查公司負責檢測地下石油資源儲量。
GeoSurvComp works with one large rectangular region of land at a time, and creates a grid that divides the land into numerous square plots. GeoSurvComp每次在一個大矩形區域中工作,創建一個網格,將土地劃分為許多方形耕地。
It then analyzes each plot separately, using sensing equipment to determine whether or not the plot contains oil. 然後分別分析每一個油井,使用傳感設備來確定該油井是否包含石油。
A plot containing oil is called a pocket. 一塊油井有油著稱為一塊油田。
If two pockets are adjacent, then they are part of the same oil deposit.
如果兩塊油田是相鄰的,且他們是相鄰的。 Oil deposits can be quite large and may contain numerous pockets. 石油資源可能很大,可能包含眾多的油井。
Your job is to determine how many different oil deposits are contained in a grid.
你的工作是確定有多少不同的油田被包含在一個網格。
Input The input file contains one or more grids. 輸入文件包含一個或多個網格。
Each grid begins with a line containing m and n, the number of rows and columns in the grid, separated by a single space. 每一個網格的第一行,分別是m和n,表示網格是m行n列,每兩個數字用一個空格隔開。 If m = 0 it signals the end of the input; otherwise 1 <= m <= 100 and 1 <= n <= 100. 如果m=0著輸入結束否著1 <= m <= 100 and 1 <= n <= 100。 Following this are m lines of n characters each (not counting the end-of-line characters). 每一行有n個字符(不包括回車符); Each character corresponds to one plot, and is either `*', representing the absence of oil, or `@', representing an oil pocket.
每一個字符都要相對應的油田,“*”表示沒有油井,“@”表示一個油井。
Output For each grid, output the number of distinct oil deposits. 對於每一個網格,輸出不同的石油資源的數量。
Two different pockets are part of the same oil deposit 對於不同的油井, if they are adjacent horizontally, vertically, or diagonally. 如果在水平,垂直,斜角是相鄰的,那麼表示兩個油井是一片油田。
An oil deposit will not contain more than 100 pockets.
一塊油田最多包含100塊油井。
