order to implement this method, we need to remember the size of each tree. Because an array is actually used, you can let the array of each root contain a negative value for the size of its tree. In this way, the initial array representation is 1. When a union is executed, the size of the tree is checked, and the new size is the original size. This is not difficult to achieve, and does not require additional space, and its average speed is fast.2. route compression (path compression). methods t
