据我所知,有三种常用的表示图的方法: MatrixAdjacency 邻接列表边缘列表也就是说,我在LeetCode上解决的问题通常使用矩阵,解决方案需要DFS或BFS。例如,给定下面的矩阵,在左、右、上、下(但不是对角线)时,查找目标字符串是否存在。 [ [‘a’,‘p’,’p’], [‘e’,’a’,’l’], [‘r’,’t’,’e...

Gaps, the special character Σ (Σ is an integer that does not appear as a gap) and other integers are encoded using the ad-hoc π-code described in the next section. When a gap g could be negative (as with degrees), then we encode 2g if g is positive, and 2|g| − 1 when ...
