In computer science, a y-fast trie is a data structure for storing integers from a bounded domain. It supports exact and predecessor or successor queries in time O(log log M), using O(n) space, where n is the number of stored values and M is the maximum value in the domain.
predecessor(x), which returns the largest element in S strictly smaller than x; successor(x), which returns the smallest element in S strictly greater than x; In addition, data structures which solve the dynamic version of the problem also support these operations: insert(x), which adds x to the set S; delete(x), which removes x from the set S
The successor function is part of the formal language used to state the Peano axioms, which formalise the structure of the natural numbers.In this formalisation, the successor function is a primitive operation on the natural numbers, in terms of which the standard natural numbers and addition are defined.

Suppose were primitive recursive, then the unary function defined by () = ((,)) would also be primitive recursive, as it is defined by composition from the successor function and . But then g {\displaystyle g} occurs in the enumeration, so there is some number n {\displaystyle n} such that g = f n {\displaystyle g=f_{n}} .
"A binary tree is threaded by making all right child pointers that would normally be null point to the in-order successor of the node (if it exists), and all left child pointers that would normally be null point to the in-order predecessor of the node." [1] This assumes the traversal order is the same as in-order traversal of the tree. However ...

Within each succession box, one or more lines may be created. One {{Succession box}} is used for each line, and parameters are used to insert data into the template: "before" for the predecessor of the subject, "title" for the subject's title, "years" for the time period during which they held the title, and "after" for the name of their successor.
