subject

[ Simple 、 recursive ]

Answer key

Depth of tree = max( Left subtree depth , Right subtree depth )+1

function TreeDepth(pRoot)
{
    
    // Recursive export 
    if(pRoot===null) return 0;
    let left = TreeDepth(pRoot.left);
    let right = TreeDepth(pRoot.right);
    return 1 + (left>right?left:right);
}

And the method of hierarchical traversal , To be added ……
