Sneakily using macros In a code golf challenge, you are tasked to use as small bytes as possible. However, it's considered unacceptable in a language like C to use macros to hide code or shorten i...
Java (JDK), 311 301 296 bytes interface A{static void main(String[]x){String a=" bottle",b=" of beer",c=" on the wall. ",e;for(int i=99;i>0;i--){e=i>1?"s":"";System.out.println(i+a+e+b+c+(...
Use for(;;) instead of while(true) The title's self-explanatory. A byte saver.
This is a list of golfing tips for the language known as Java. If you have a tip, add it in!
Python 3, 80 77 75 72 bytes def f(): yield 1;l=[*range(2,236425)] while l:yield l[0];del l[::l[0]] Try it online! Prints out the whole sequence. I did my best to get the biggest number t...
Challenge Write a program that prints its reversed self. For example, if your code is foo() Then it'll output: )(oof Make sure that the quine is a valid one, as defined here: No cheatin...
Use a+=[b] instead of a.append(b) The title says it all. a=[];b=10;print(a) a+=[b];print(a) Try it online!
import* You can import some libraries and if you find yourself using: from lib import * Remove the space between import and *, because it works for whatever reason.
Replace for loops with string multiplication Let's say we have: for i in range(6):print(end="#") Try it online! This basically outputs # 6 times, which is self-explanatory in the code itsel...
Challenge What do computers understand? That's right, binary. All files are turned into binary digits when you run them, but what if I suggest giving you an int then turn it into it's binary value...
Forth (gforth), cracked by user, 20 bytes .( Cops and Robbers) Try it online!
There's another type of challenge named code bowling, and I've never heard of it, or even if I did, still don't know how it works. I'm willing to write challenges on code bowling and I want to know...
I'm not a golfer, I know, but I do have wanted to make a programming language back then. The name is BMPL (Builder's Multi-Purpose Language) and is currently a library I made in C (clang). It's not...
In this challenge, add 2 integers, but if both the integers are 2, output 5. Shortest code in each language wins! Example ungolfed program in Python 3.x def add(x, y): if x == 2 and y == 2: ...
Just curious, but this might help other users, so I'm placing at Meta. A popularity-contest is a non-object winning criteria challenge that is based on having the highest scored answer of the chal...
Lua, 35 32 bytes print("Hello, "..io.read().."!") Try it online! Golfed 3 bytes thanks to @Moshi's advice.
Ruby, 24 21 18 bytes p"Hello, #{gets}!" Try it online! Golfed down 3 bytes thanks to @snail_'s advice. Golfed down 3 bytes thanks to @south's advice.
Python 3, 196 195 145 102 91 89 87 79 bytes x=input();x+=x[::-1];i=-1 for c in x[:-1]:print(c*(i>-1)+" "*i+c);i+=1 print(x) Try it online! Golfed 50 bytes thanks to @celtschk's advice. ...
Lua, 126 118 bytes p=print for i=1,100 do if i%15==0 then p"FizzBuzz"elseif i%3==0 then p"Fizz"elseif i%5==0 then p"Buzz"else p(i)end end Try it online!
Python 3, 349 261 160 bytes a="re y gree br sc bla oc pe rub ol v f li go ch m cre cri si ro a le rus grey pu w pi or blu".split() def f(b):return[j for i in a for j in b if j[:len(i)]==i] T...
Challenge Make a program that takes input of an integer that's $n > 1$ and print out a staircase using a specific character for stair basing (hashes (#) for demonstration; you can use spaces,...
Use lambdas instead of functions At most times, lambdas tend to make smaller code, which is helpful in golfing. Assigning a lambda is easy, just do: lambda f:whatever There are many answers th...
Assign floats while leaving out zeroes Python allows such strange assignment. You can save bytes by removing the number preceding . if it's only 0: i=.5 print(i) Try it online! The same g...
