z()

Read(296) Label: locate, evenly split,

Description:

Locate a member of a set that is split into multiple subsets.

Syntax:

z(i,n)

z(i,n)

Divide a set of natural numbers into multiple subsets, the length of each is k, and find the subset in which the ith member is located

z(i,k,n)

Divide a set cointaining n members evenly into k subsets and find the subset in which the ith member is located

Note:

 For a set with a specified length, the sequence number of the to-be-located member should be within the length, i.e. i<=n.

Parameters:

i

Integer; the sequence number of a member and i<=n

k

Integer; the length of a subset

n

An integer, which is the length of a set

Return value:

Integer

Example:

z(13,5)

z(13,5,19)
