Create a Tree class so I can grow a happy little tree. The tree has a trunk and branches which grow in unit sizes. Branches can start at the current trunk height. All branches grow simultaneously,

Methods to include:

• Tree() - Constructor (trunk starts with height of 1 and no branches)
• GrowTrunk() - Increase trunk height by 1 (add a new level on top of the tree similar to adding layers to a cake)
• NewBranch() - Add a new branch at the current height (multiple separate branches can be added at each level)
• GrowBranches() - All existing branches increase in length by 1
• Ouch(int n) - The nth oldest branch is removed (the input is 1-indexed, and must be validated: if a branch does not exist or the input is not positive, do nothing)
• Description() - Returns a string describing all the properties of the tree as seen below (replace the _ with appropiate values, )

"The tree trunk is {HEIGHT} unit(s) tall! There are {BRANCHES_COUNT} branch(es) that have position(s): {POSITIONS...} and length(s): {LENGTHS...}!"

Where HEIGHT and BRANCHES_COUNT are integers, POSITIONS... and LENGTHS... are comma-separated lists.

If there are no branches, the following string should be returned instead:

"The tree trunk is {HEIGHT} unit(s) tall! There are 0 branch(es)!"

Preloaded code for class structure:

public interface ITree
{
  void GrowTrunk();
  void GrowBranches();
  void NewBranch();
  void Ouch(int n);
  string Description();
}
