What is code golf?
Code golf is a type of recreational computer programming competition in which participants strive to achieve the shortest possible source code that implements a certain algorithm. Playing code golf is known as "golf scripting". Code golf challenges and tournaments may also be named with the programming language used (for example, Perl golf ).
What are some examples of golfing languages?
Dedicated golfing languages. Several new languages have been created specifically with code golfing in mind. Examples include GolfScript, Flogscript and Vyxal, which are Turing-complete languages which provide constructs for concisely expressing ideas in code. Because golfing languages compete for extreme brevity, ...
How to tell if there is a dress code for golf?
A good indicator of whether there is a dress code is the price of the course you plan to play. The higher the green fees, the more likely there is to be a dress code for golfers.
Do golf courses have dress codes?
To recap: Yes, many golf courses—especially non-municipal courses— do have golf dress codes. If you wear a shirt with a collar and Dockers-style pants or shorts, you'll meet the dress code of 95-percent of courses. But always call ahead before playing a new course and ask for the specifics.
Can you wear spikes on golf shoes?
Most golf courses have outlawed metal spikes. Make sure you're wearing golf shoes with soft spikes or other non-metal golf cleats; or wear a soft-soled shoe of some other type (tennis shoes, for example—never anything with a hard heel).
Who is Brent Kelley?
Brent Kelley is an award-winning sports journalist and golf expert with over 30 years in print and online journalism. Many golf courses do have dress codes. But not all of them. Many municipal golf courses do not have dress codes—except, of course, in the sense that you must be dressed! (No shirt, no service.)
Do golf courses have dress codes?
Not only is there an unspoken etiquette, but most golf courses have a dress code that requires particular attire in order to play. These dress codes are not as restrictive as the rules for PGA Tour or LPGA Tour players, but they are designed to ensure that amateur players adhere to a certain protocol to help maintain the game's traditions.
What is golf shoes?
Footwear is considered part of the game's equipment. Golf shoes will help stabilize a player's swing, allow for traction when walking and provide comfort during a round that can last several hours. These shoes include spikes on the soles.
Why is golf clothing important?
Golf clothing is important from a comfort standpoint , and many courses have strict rules about attire. The clothing in golf is a part of the decorum of the game, perhaps more so than any other sport. Not only is there an unspoken etiquette, but most golf courses have a dress code that requires particular attire in order to play.
What is the purpose of golf shoes?
Golf shoes will help stabilize a player's swing, allow for traction when walking and provide comfort during a round that can last several hours. These shoes include spikes on the soles.
Can you wear shoes on a golf course?
Sneakers or running shoes are sometimes allowed on golf courses, but not always. Sandals, street shoes and boots are not permitted on ...
Why do golfers wear socks?
Over the years, socks have become an important part of golf attire, mainly because advances in fibers help to keep a golfer comfortable and his feet dry. Golf socks come in a variety of styles.
Conditionals
A good place to start looking for those pesky characters that should be removed: the if statements and their lengthy conditions:
Output
One might say there’s nothing left to improve in such a short line of code like:
For Loops
Just like if statements, for-loops are a gold mine when it comes to code golf. If there’s one thing you should always try to avoid, it’s having nested for– loops.
Variables and Conversion
Converting from one type to another or storing an excessive amount of data in variables can cost a lot of characters. A good example is converting from float to int after performing division:
Lists
Saving the best for last, we have lists, and a good replacement for almost every commonly used list method. Lengthy methods like append or extend take up way too much space to be used in code golf, and we can immediately start saving characters on the line where we created our list:
Overview
Code golf is a type of recreational computer programming competition in which participants strive to achieve the shortest possible source code that solves a certain problem. Code golf challenges and tournaments may also be named with the programming language used (for example, Perl golf).
History
The length of the shortest possible program that produces a given output (in any fixed programming language) is known as the Kolmogorov complexity of the output, and its mathematical study dates to the work of Andrey Kolmogorov in 1963. Code golf, however, can be more general than this, as it often specifies a general input-output transformation that must be performed rather than asking for a single output with no input.
Etymology
The term "code golf" is derived from the similarity of its goal with that of conventional golf, where participants seek to achieve the lowest possible score, rather than the highest, as is the standard in most sports and game scoring systems. While conventional golf players are trying to minimize the number of club strokes needed to complete the course, code golfers are striving to reduce the number of key strokes necessary to write the program.
Dedicated golfing languages
Several new languages have been created specifically with code golfing in mind. Examples include GolfScript, Flogscript and Vyxal, which are Turing-complete languages which provide constructs for concisely expressing ideas in code. Because golfing languages compete for extreme brevity, their design sacrifices readability, which is important for practical production environments, and therefore they are often esoteric. Sometimes, however, a language is designe…
Types of code golf
Some code golf questions, such as those posed on general programming sites, may not require implementation in a specific programming language. However, this limits the style of problems that it is possible for the problem designers to pose (for example, by limiting the use of certain language features). In addition, the creation of such "open" questions has resulted in the design of code golf specific programming language dialects such as REBMU (a dialect of REBOL). Both on…
