Another solution for old coder task "second unique smallest value" - https://www.geeksforgeeks.org/second-unique-smallest-value-of-given-binary-tree-whose-each-node-is-minimum-of-its-children/

// Here's a sample binary tree node class:
open class BinaryTreeNode constructor(var value: Int) {
var left: BinaryTreeNode = Empty
protected set
var right: BinaryTreeNode = Empty
protected set
fun insertLeft(leftValue: Int): BinaryTreeNode {
check(leftValue >= 0) { "Expected only positive values" }
this.left = BinaryTreeNode(leftValue)
