Figure 1. Finding the shortest path in a graph using optimal substructure; a straight line indicates a single edge; a wavy line indicates a shortest path between the two vertices it connects (among other paths, not shown, sharing the same two vertices); the bold line is the overall shortest path from start to goal.
The difference here is that you're writing for a new audience, writing with a unique encyclopedic tone, and you're doing it all on a new platform. Learning about editing basics can seem overwhelming, so we've created this online orientation for student editors to simplify what you need to know to contribute successfully to Wikipedia.
In computer science, syntactic sugar is syntax within a programming language that is designed to make things easier to read or to express. It makes the language "sweeter" for human use: things can be expressed more clearly, more concisely, or in an alternative style that some may prefer.
This can simplify the definition of some functions. For example, writing a function to output the first n square numbers in Racket can be done accordingly: ( define ( first-n-squares n ) ( map ( lambda ( x ) ( * x x )) ;;; A function mapping x -> x^2 ( range n ))) ;;; List of the first n non-negative integers
Introduced in Python 2.2 as an optional feature and finalized in version 2.3, generators are Python's mechanism for lazy evaluation of a function that would otherwise return a space-prohibitive or computationally intensive list. This is an example to lazily generate the prime numbers:
a := (1 + 2) * 5. To a human, this seems a fairly simple and obvious calculation ("one plus two is three, times five is fifteen"). However, the low-level steps necessary to carry out this evaluation, and return the value "15", and then assign that value to the variable "a", are actually quite subtle and complex.
Rosemary Oil. A very common oil included in natural hair growth products, studies have noted the efficacy of rosemary in promoting hair growth. In one study, results showed that rosemary oil may ...
Similar to the examples described above, we consider x, y, φ to be independent uniform random variables over the ranges 0 ≤ x ≤ a, 0 ≤ y ≤ b, − π / 2 ≤ φ ≤ π / 2 . To solve such a problem, we first compute the probability that the needle crosses no lines, and then we take its complement.
