Balanced parenthesis sequences
In this page we provide the balanced parentheses representation of several trees. The balanced parentheses representation of a tree consists of a depth-first preorder traversal of the tree, writing an opening parenthesis when visiting a forward edge (parent to child), and a closing parenthesis when visiting a backward edge (child to parent). Thus, a balanced parentheses representation of a tree with n nodes has 2n parentheses.
