It is clear that the minimum distance traveled by the DFS sequence is the total distance.If not modified, it is actually a virtual tree.Now that the changes have been brought ... In fact, it is the DFS sequence that maintains the key points.It's good to maintain a balance tree, which involves inserting, deleting, finding the predecessor, and finding the maximum minimum value.It's a two-point journey and an LCA.(So this problem becomes treap full board ...)1#include 2#include 3#include 4#include

can also draw SVG rectangles with rounded corners. The rx and ry attributes are used to determine the size of the rounded corner of a rectangle. The rx attribute determines the width of the rounded corner, and the ry attribute determines the width of the rounded corner. In the following example, the rounded corners of the three rectangles are set to 5 pixels, 10 pixels, and 15 pixels respectively. Observe
