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...
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 ...
I think everything strictly needed to write or judge a solution should never be hidden. If you feel it is too large, think about how to shorten it. Information that is not strictly necessary can b...
C (gcc), 46 bytes f(int*a){return *a<0|a[1]<0||*a==a[1]&f(a+1);} This takes an array that is terminated by a negative number (which is not part of the list content, just like the te...
Some additional cosiderations on using the sandbox: First, a migration mechanism might encourage good behaviour, for example by migration being only possible if the post has a minimal score, and/o...
Python 3, 48 bytes def f(n,d):return f"[{(50*n+d//2)//d*'|':-<50}]" Try it online!
Contestants should read from standard input and write to standard output. This is because almost all programming languages, including most esoteric programming languages, allow reading from standar...
C (gcc), 64 62 bytes Saved 2 bytes thanks to m90 in the comments. i;f(char*s){i=atoi(s)>>4;return'A'+(i&8?i&4?i&2?i%2+3:2:1:0);} Try it online!
Use pointer arithmetic and \0 with string literals In C, strings are just zero-terminated character arrays, which means you can play tricks with pointer arithmetic. For example, the line char*s=a...

Reorder expressions in order to save whitespace Consider the following code: if c=='U':c='X' The space between if and c obviously cannot be removed, as that would merge them to the identifier ...

If you have any tips for golfing in Python, add them as answers to this post.
Unlambda, 1 solution Since Unlambda code that does something always contains the backtick character, there cannot be more than one solution. ```.2.5.6i
