bst-typed v1.52.0

What

Brief

This is a standalone BST (Binary Search Tree) data structure from the data-structure-typed collection. If you wish to access more data structures or advanced features, you can transition to directly installing the complete data-structure-typed package

How

install

npm

npm i bst-typed --save

yarn

yarn add bst-typed
