A for loop is a programming construct that allows repeated execution of a block of code, called the loop body, until a condition is met. Learn how to use for loops in different languages, such as C, Fortran and Python, and how to handle loop variables, counters and break statements.
Control flow is the order in which statements, instructions or function calls of an imperative program are executed or evaluated. Learn about the primitives, categories and proposed control structures of control flow in computer science.
A closure is a technique for implementing lexically scoped name binding in a language with first-class functions. Learn the history, applications, and implementation of closures, and how they differ from anonymous functions and other closure-like constructs.
The trapezoidal rule is a technique for numerical integration, i.e., approximating the definite integral of a function by a trapezoidal area. Learn about its history ...
Learn how Newton's method (also called Newton–Raphson) is used to find the roots or critical points of a differentiable function. See the geometric interpretation, the convergence, the modifications and the caveats of this iterative method.
A control-flow graph (CFG) is a graph representation of all paths that might be traversed through a program. Learn how to construct, analyze and optimize CFGs with examples, definitions and properties.
Binary search Visualization of the binary search algorithm where 7 is the target value Class Search algorithm Data structure Array Worst-case performance O (log n) Best-case performance O (1) Average performance O (log n) Worst-case space complexity O (1) Optimal Yes In computer science, binary search, also known as half-interval search, logarithmic search, or binary chop, is a search ...
In computational number theory, the index calculus algorithm is a probabilistic algorithm for computing discrete logarithms. Dedicated to the discrete logarithm in ( Z / q Z ) ∗ {\displaystyle (\mathbb {Z} /q\mathbb {Z} )^{*}} where q {\displaystyle q} is a prime, index calculus leads to a family of algorithms adapted to finite fields and to ...
