Description
The depth or height of a binary tree. The depth (or height) of a binary tree is the maximal depth (or height) of one of its vertices. The '''height''' of a vertex is the number of edges on the longest path between that node and a leaf. The '''depth''' of a vertex is the number of edges from the vertex to the root. See [1] and [2] for this terminology. The depth (or height) of a tree T can be recursively defined: depth(T)=0 if T is empty and depth(T)=1+max(depth(L),depth(R)) if T is nonempty with left and right subtrees L and R, respectively. The upper and lower bounds on the depth of a binary tree T of size n are log2(n)≤depth(T)≤n.

Description
The length of the first row of the shifted shape of a permutation. The diagram of a strict partition Ī»1<Ī»2<⋯<λℓ of n is a tableau with ā„“ rows, the i-th row being indented by i cells. A shifted standard Young tableau is a filling of such a diagram, where entries in rows and columns are strictly increasing. The shifted Robinson-Schensted algorithm [1] associates to a permutation a pair (P,Q) of standard shifted Young tableaux of the same shape, where off-diagonal entries in Q may be circled. This statistic records the length of the first row of P and Q.
