Bash, 20 18 bytes Saved two bytes by removing the quotes; the code works well without them. echo Hello, `cat`! Try it online!
C (gcc), 35 32 bytes Saved 3 bytes thanks to Lundin f(n){n&&f(n/2);putchar(n&1|48);} This solution exploits that leading zeros, while not required, are also not forbidden by the ...
C (gcc), 50 bytes f(int(*o)(i,j),int n){return n-1?o(f(o,n-1),n):1;} Try it online!
Unlambda, 1 solution Since Unlambda code that does something always contains the backtick character, there cannot be more than one solution. ```.2.5.6i
C (gcc), 33 31 bytes f(x,y){return x+y+(x==2&y==2);} Try it online! Saved two bytes thanks to Shaggy
Given two strings, I define their product as follows: If any of the two strings is empty, the product is the empty string. If the second string consists of a single character, the result ...

Python 3, 76 71 bytes Saved 5 bytes thanks to user def f(p,n):l=[n*p//q for(p,q)in p if n%q<1];return f(p,l[0])if l else n Try it online! This code assumes that the fractions are given a...
The task is to generate the text of Lewis Caroll's Jabberwocky. The text, quoted from Wikipedia, is as follows (I've replaced a non-ASCII character with ASCII, otherwise it's direct copy&paste...
