In mathematics, an empty sum, or nullary sum, [1] is a summation where the number of terms is zero. The natural way to extend non-empty sums [2] is to let the empty sum be the additive identity. Let , , , ... be a sequence of numbers, and let = = = + + be the sum of the first m terms of the sequence. This satisfies the recurrence
0 is represented by the empty sum. 0 = F −1 + F −2 , for example, so the uniqueness of the representation does depend on the condition that no two consecutive negafibonacci numbers are used. This gives a system of coding integers, similar to the representation of Zeckendorf's theorem.
In mathematics, an empty product, or nullary product or vacuous product, is the result of multiplying no factors.It is by convention equal to the multiplicative identity (assuming there is an identity for the multiplication operation in question), just as the empty sum—the result of adding no numbers—is by convention zero, or the additive identity.
Flood-fill (node): 1. Set Q to the empty queue or stack. 2. Add node to the end of Q. 3. While Q is not empty: 4. Set n equal to the first element of Q. 5. Remove first element from Q. 6. If n is Inside: Set the n Add the node to the west of n to the end of Q. Add the node to the east of n to the end of Q.

Letting slip a 1-0 lead and securing only a draw dealt a blow to Arsenal’s Premier League title hopes as the Gunners now sit five points behind league leader Liverpool, which has two games in hand.
For every set X, there is a unique function, called the empty function, or empty map, from the empty set to X. The graph of an empty function is the empty set. [note 5] The existence of empty functions is needed both for the coherency of the theory and for avoiding exceptions concerning the empty set in many statements.
