Integer Integer An integer (from the Latin "integer" meaning "whole") is a number that can be written without a fractional component. For example, 21, 4, 0, and −2048 are integers, while 9.75, , and are not. The set of integers consists of zero (), the positive natural numbers (, , , …), also called "whole numbers" or "counting numbers", and their additive inverses (the negative integers, i.e., −1, −2, −3, …). The set of integers is often denoted by a boldface Z ("") or blackboard bold formula_1 (Unicode U+2124 ℤ) standing for the German word "Zahlen" (, "numbers"). The integers form
Bead sort bead sort is unusual in that in worst case it can perform faster than "O"("n" log "n"), the fastest performance possible for a comparison sort in worst case. This is possible because the key for a bead sort is always a positive integer and bead sort exploits its structure. This example is written in Python. The strategy for "dropping" the beads may be slightly different, but it does the same job. def Gravity(obj): """how it does it: it counts the "beads" in each column, then uses those numbers to make a new set of rows. Adding up the beads in
