The last line is an unnamed lambda function that takes a list and returns 1 for "truthy-under-Ȧ" and 0 for falsey. lD saves the next character, then deletes the rest of the line.3|a01 Writes 01 after the third character.Thus, it's just a problem for identifying if the third character is a 0. The possible way for a 0 to be at the third position is if it is the empty array. Else, this will stop on the first line, leaving the line (array) 0Īt this point, all that's left to do is to identify the empty array and output 0 if it's present, otherwise ignore it.This leaves 0 on the first line, which is an empty array.If 0 is in the array, this will stop on the second line.#dd search for the word "0", going backwards in the document and delete the line it's containing.A 0 Writes some stuff preceding the array.i 0 Writes some stuff preceding the array.i 0A 0h#dd0%r602x$hd0Įxpects the array to be in the first and only line of the file and the cursor to be on the first character. Had to add a bunch of keystrokes to take care of multiple zeros and the empty array. VIM: 16 keystrokes 28 keystrokes 26 keystrokes This has been discussed in one of my answers before, and it was concluded that it is allowed in the default rules to return different truthy and falsy values for different inputs, but for some reason OP forbid it here and there.

Jelly golf it code#
May the shortest code in bytes win! Truthy test cases You are encouraged to post answers using both array and string manipulation, even if one is significantly shorter than the other. If your language has a built-in that is itself a valid submission to this challenge, you may not use it in your answer. If your language has several ways of representing jagged arrays (e.g., lists and tuples), you only have to support one of them. If (and only if) your language cannot represent jagged arrays natively, you may take a string representation of the input, using the canonical syntax of any pre-existing programming language. In particular you cannot assume that the first element of the array will be preceded by a space. However, you must use the canocical representation of your language, as returned by repr or similar.
Jelly golf it full#
Since full programs can only take string representations of arrays as input, this is allowed. The truthy and falsy values must be consistent for all inputs, i.e, all arrays for which Ȧ returns 1 must map to the same truthy value, and all arrays for which Ȧ returns 0 must map to the same falsy value. Your submission must abide to the following rules. In a programming language of your choice, write a full program or a function that takes a possibly empty, possibly jagged array of integers as input and prints or returns a truthy or falsy value that indicates if Ȧ would return 1 or 0, respectively. Ȧ takes an array as input and returns 1 if the array is non-empty and does not contain the number 0 (integer, float, or complex) anywhere in the tree structure otherwise, it returns 0.įor example, the array ] is truthy because it is non-empty and contains no zeroes, but ] is falsy because it contains a 0 at the innermost level. For a fast challenge, try one of our mini-golf challenges, which offer several types of putt-putt courses.Inspired by Octave's (and, by extension, MATL's) very convenient interpretation of truthy/falsy matrices, Jelly got the Ȧ (Octave-style all) atom. Practice individual skills such as driving and putting in specialized games, and try to set new records! Even play games which alter physics, always changing and keeping you on your toes. In some challenges, you can play on Mario-themed courses and other magical lands. Our golf games also include alternate and arcade challenges, such as space and gravity-altering levels. Practice your backswing, perfect your aim, and hit balls like Tiger Woods! Play any type of golf challenge, including match play, stroke play, and skins. Avoid deep sand traps, stay away from water hazards, and try to sink the final putt in the least amount of strokes possible! Our collection will test every aspect of your craft, from long drives to chips to putts. You can choose from plenty of courses, which offer realistic holes and exciting challenges. Our golf games offer many hours of 9- and 18-hole entertainment.
