Description
The balance of a binary word. The balance of a word is the smallest number q such that the word is q-balanced [1]. A binary word w is q-balanced if for any two factors u, v of w of the same length, the difference between the number of ones in u and v is at most q.

Description
The depth of the binary word interpreted as a path. This is the maximal value of the number of zeros minus the number of ones occurring in a prefix of the binary word, see [1, sec.9.1.2]. The number of binary words of length n with depth k is \binom{n}{\lfloor\frac{(n+1) - (-1)^{n-k}(k+1)}{2}\rfloor}, see [2].
