The process of solving ideas: This is the most classic deep search topic. The teacher also spoke in class, so the idea naturally has. The DFS function is written out and it's all over. Impression: The example in class is also the most classic part. F

panning, and the following is an example of scaling to understand the control of scalingThrough the API provided by Android we can invoke Setscale, Prescale, Postscale to change the value of mscale_x and mscale_y to achieve scaling effect So as long as we understand the difference between the three methods of Setscale, Prescale and Postscale, we can simply zoom control. 1, Setscale (Sx,sy), the matrix will first be set to the diagonal matrix, which

the top is modified to enumerate the edges to find D value, the complexity of O (N2). In fact, the complexity of the KM algorithm can be achieved O (N3). We give each y vertex a "slack" function slack, which is initialized to infinity each time we start looking for an augmented path. While looking for an augmented path, when checking for edges (i,j), if it is not in the equal sub-graph, let slack[j] become the smaller value of the original value and a [i]+b[j]-w[i,j]. This way, when you modify
