In computer programming, indentation style is a convention, a.k.a. style, governing the indentation of blocks of source code.An indentation style generally involves consistent width of whitespace (indentation size) before each line of a block, so that the lines of code appear to be related, and dictates whether to use space or tab characters for the indentation whitespace.
These correspond to the different ways that parentheses can be placed to order the multiplications for a product of 5 matrices. For the example below, there are four sides: A, B, C and the final result ABC. A is a 10×30 matrix, B is a 30×5 matrix, C is a 5×60 matrix, and the final result is a 10×60 matrix.
McCarthy published Lisp's design in a paper in Communications of the ACM on April 1, 1960, entitled "Recursive Functions of Symbolic Expressions and Their Computation by Machine, Part I" [19]. [20] He showed that with a few simple operators and a notation for anonymous functions borrowed from Church, one can build a Turing-complete language for ...
Video: Keys pressed for calculating eight times six on a HP-32SII (employing RPN) from 1991. Reverse Polish notation (RPN), also known as reverse Łukasiewicz notation, Polish postfix notation or simply postfix notation, is a mathematical notation in which operators follow their operands, in contrast to prefix or Polish notation (PN), in which operators precede their operands.
The basic problem considers all trials to be of one "type". The birthday problem has been generalized to consider an arbitrary number of types. [20] In the simplest extension there are two types of people, say m men and n women, and the problem becomes characterizing the probability of a shared birthday between at least one man and one woman ...
In the author–date method (Harvard referencing), [4] the in-text citation is placed in parentheses after the sentence or part thereof that the citation supports. The citation includes the author's name, year of publication, and page number(s) when a specific part of the source is referred to (Smith 2008, p.
The reason for the question mark at the end of the name was because when lead singer and guitarist Andy Cairns was writing out the spines for the cassettes to send off to the record companies, he began writing too far to the left, so to centre the writing and make it look more professional, he added a question mark to the end and it stuck with ...
For example, in Python, raw strings are preceded by an r or R – compare 'C:\\Windows' with r'C:\Windows' (though, a Python raw string cannot end in an odd number of backslashes). Python 2 also distinguishes two types of strings: 8-bit ASCII ("bytes") strings (the default), explicitly indicated with a b or B prefix, and Unicode strings ...
