Algorithms & data structures

huge sparse array

Computer science; Algorithms & data structures

Let N be the number of items to store and R be the size of the range of key values; R >> N. Allocate, but don't initialize, two arrays: an item array I, where

orthogonal lists

Computer science; Algorithms & data structures

Lists that share items, but are structurally independent.

information theoretic bound

Computer science; Algorithms & data structures

lower bounds on the execution of a computation based on the rate at which information can be accumulated.

symmetric set difference

Computer science; Algorithms & data structures

Members which are in either set, but not in both. That is, for sets A and B, it is (A - B) ∪ (B - A).

Merge n sorted sequences of different lengths into one output while minimizing reads. Only two sequences can be merged at once. At each step, the two shortest sequences are merged. Formal Definition: ...

simple merge

Computer science; Algorithms & data structures

Merge n sorted streams into one output stream. All the stream heads are compared, and the head with the least key is removed and written to the output. This is repeated until all streams are empty.

ideal merge

Computer science; Algorithms & data structures

Merge n sorted streams into one output stream. To begin the streams are sorted by the value of the head element of each. Then the head of the first stream, which is the least since the streams were ...
