There are multiple different ways to create a tree including: starting with and empty tree and adding or removing values using + or - buttons, using tree string structure to describe a particular tree then perform operations on it, and generating a random tree using random tree generator by pressing Generate button. Here are the steps needed to perform the most common operations:

Building a tree

There are multiple ways to build a tree including:

1. By inserting numbers

• Add the first number into tree description and press go
• Add other numbers into add a number text input and press +

2. By tree sequence

• Enter a sequence of additions and deletions separated by commas
• Press GO

What is a tree sequence?

It is a sequence of comma-separated numbers that describe insertions and deletions that happened to the tree. - To add an insertion into the sequence just add the number. - To add a deletions into the sequence add letter 'd' before the number.

  Ex: 1,2,9,10,d2,11,15,d10

3. By tree description string

• Enter a tree string into 'Describe a tree' text field
• Press GO

What is tree string?

  It is a string that explains the tree such that:
  - numbers separated by commas and between {'{}'} belonges to the same node
  - Each node's children are separated by commas and placed between ()

  Example tree string : {'{5,7}({3}{6}{8,9})'}

  Corresponding tree :

                     {5,7}
                   /   |   \
                  {3} {6} {8,9}
