A linkcut tree is a type of data structure capable of merging link operation and splitting cut operation data sets in ologn amortized time, as well as finding which tree an element belongs to in ologn amortized time. As depicted, the unbalanced node becomes the right child of its left child by performing a right rotation. And the nodes are connected to other nodes through what are called as the edges.
