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.
Python list comprehensions (such as [x*x for x in range(10)] for a list of squares) and decorators (such as @staticmethod). In Haskell, a string, denoted in quotation marks, is semantically equivalent to a list of characters. An optional language extension OverloadedStrings allows string literals to produce other types of values, such as Text ...
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
In computer science, extended Backus–Naur form (EBNF) is a family of metasyntax notations, any of which can be used to express a context-free grammar.EBNF is used to make a formal description of a formal language such as a computer programming language.
Python supports a wide variety of string operations. Strings in Python are immutable, so a string operation such as a substitution of characters, that in other programming languages might alter the string in place, returns a new string in Python. Performance considerations sometimes push for using special techniques in programs that modify ...
According to the New York Times, here's exactly how to play Strands: Find theme words to fill the board. Theme words stay highlighted in blue when found.
Divide-and-conquer approach to sort the list (38, 27, 43, 3, 9, 82, 10) in increasing order. Upper half: splitting into sublists; mid: a one-element list is trivially sorted; lower half: composing sorted sublists. The divide-and-conquer paradigm is often used to find an optimal solution of a problem.
The Huffington Post reached out to historians across the country to create a list of women who deserve more recognition for their accomplishments. Women may not always get the historical credit their male counterparts do, but as these women show, they were always there doing the work.
