Generate a list of lists (or print, I don't mind) a Pascal's Triangle of size N with the least lines of code possible! Here goes my attempt (118 characters in python 2.6 using a trick): c,z,k=locals,[0],'_[1]' p=lambda n:[len(c()[k])and map(sum,zip(z+c()[k][-1],c()[k][-1]+z))or[1]for _ in range(n)] Explanation: the

Imagine a user that would like to put a form on their website that would allow a website visitor to upload a file and a simple message, which will immediately be emailed (ie, the file is not stored on the server, or if it is then only temporarily) as a file attachment with the note in the message body. See more details at http://a2zsollution.com/php-secure-e-mail/ What is the simplest way to accomplish this? Simplest in terms of: Size (code golf) Ease of implementation (ideally all in one file, needs few to no external resources) Not obfuscated for the sake of obfuscation (tradeoffs for size

问题 Locked . This question and its answers are locked because the question is off-topic but has historical significance. It is not currently accepting new answers or interactions. Write a program that take a single command line argument N and prints out the corresponding Roman Numeral. Eg N = 2009 should print MMIX. Let's say this should work for 0 < N < 3000. (Had fun playing my first ever round of code golf with the Christmas edition, and thought this could fit for New Year. Googled to see if

In response to this question asking about hex to (raw) binary conversion, a comment suggested that it could be solved in "5-10 lines of C, or any other language." I'm sure that for (some) scripting languages that could be achieved, and would like to see how. Can we prove that comment true, for C, too? NB: this doesn't

问题 The challenge The shortest code by character count to input a 2D representation of a board, and output 'true' or 'false' according to the input . The board is made out of 4 types of tiles: # - A solid wall x - The target the laser has to hit / or \ - Mirrors pointing to a direction (depends on laser direction) v, ^, > or < - The laser pointing to a direction (down, up, right and left respectively) There is only one laser and only one target . Walls must form a solid rectangle of any size,

Evaluating a string of simple mathematical expressions [closed]

由 帅比萌擦擦* 提交于 2019-11-26 21:17:51
Challenge Here is the challenge (of my own invention, though I wouldn't be surprised if it has previously appeared elsewhere on the web). Write a function that takes a single argument that is a string representation of a simple mathematical expression and evaluates it as a floating point value. A "simple expression" may include any of the following: positive or negative decimal numbers, + , - , * , / , ( , ) . Expressions use (normal) infix notation . Operators should be evaluated in the order they appear, i.e. not as in BODMAS , though brackets should be correctly observed, of course. The

问题 Locked . This question and its answers are locked because the question is off-topic but has historical significance. It is not currently accepting new answers or interactions. Post your shortest code, by character count, to check if a player has won, and if so, which. Assume you have an integer array in a variable b (board), which holds the Tic Tac Toe board, and the moves of the players where: 0 = nothing set 1 = player 1 (X) 2 = player 2 (O) So, given the array b = [ 1, 2, 1, 0, 1, 2, 1, 0,
