👉 A sequace is a sequence of objects that can be transformed into another sequence. These sequences are often used in computer science and mathematics to represent data structures, such as trees or graphs. For example, if we have a binary tree with nodes labeled A through Z, where each node has two children (left child and right child), then the sequace of this tree could be represented by a sequence of strings like "ABZ", "AZB", etc. Each string corresponds to a parent-child
