Pseudocode. In computer science, pseudocode is a description of the steps in an algorithm using a mix of conventions of programming languages (like assignment operator, conditional operator, loop) with informal, usually self-explanatory, notation of actions and conditions. [ 1][ 2] Although pseudocode shares features with regular programming ...
Skeleton (computer programming) Skeleton programming is a style of computer programming based on simple high-level program structures and so called dummy code. Program skeletons resemble pseudocode, but allow parsing, compilation and testing of the code. Dummy code is inserted in a program skeleton to simulate processing and avoid compilation ...
Worst-case space complexity. total, 1 auxiliary. Optimal. No. Bubble sort, sometimes referred to as sinking sort, is a simple sorting algorithm that repeatedly steps through the input list element by element, comparing the current element with the one after it, swapping their values if needed. These passes through the list are repeated until no ...
This is a pseudocode implementation of an optimal fixed-memory flood-fill algorithm written in structured English: The variables. cur, mark, and mark2 each hold either pixel coordinates or a null value NOTE: when mark is set to null, do not erase its previous coordinate value. Keep those coordinates available to be recalled if necessary.
Swap (computer programming) In computer programming, the act of swapping two variables refers to mutually exchanging the values of the variables. Usually, this is done with the data in memory. For example, in a program, two variables may be defined thus (in pseudocode ): After swap () is performed, x will contain the value 0 and y will contain ...
Graph. Worst-case performance. Tarjan's strongly connected components algorithm is an algorithm in graph theory for finding the strongly connected components (SCCs) of a directed graph. It runs in linear time, matching the time bound for alternative methods including Kosaraju's algorithm and the path-based strong component algorithm.
t. e. In computer science, a for-loop or for loop is a control flow statement for specifying iteration. Specifically, a for-loop functions by running a section of code repeatedly until a certain condition has been satisfied. For-loops have two parts: a header and a body. The header defines the iteration and the body is the code that is executed ...
Readers–writer lock. In computer science, a readers–writer ( single-writer lock, [ 1] a multi-reader lock, [ 2] a push lock, [ 3] or an MRSW lock) is a synchronization primitive that solves one of the readers–writers problems. An RW lock allows concurrent access for read-only operations, whereas write operations require exclusive access.
