What's wrong with this sequence? 9 8 7 6 5 4 3 2 1 0 89 88 87 86 85 84 83 82 81 80 79 78 77 76 75 74 73 72 71 ... Input A number n from 0 to 1000. Output A number s equal to the sum of the first n elements of the above sequence. Standard code-golf rules apply. The shortest code in bytes wins.

UTF-∞ It's 22022 and the Unicode consortium is having a problem. After the writing system of the ⮧⣝Ⅲⴄ⟢⧩⋓⣠ civilization was assigned the last Unicode block, the consortium members have been scrambling to find a new encoding to replace UTF-8. Finally UTF-∞, a proposal by Bob Rike, was adopted. UTF-...

Interpret Shue code-golf Overview Shue (simplified Thue) is a language that was designed by AnttiP for this challenge. A Shue program consists of the possible outputs and a list of string replacements. For example, the following program prints "yes" if an unary string is even: yes no 11=2 12=1 22...

In this challenge you will take as input a non-empty list of integers which will serve as the forbidden word. You must then output an infinite stream of positive numbers such that: The forbidden word never appears as a contiguous subsequence of your output. Every finite sequence of positive int...

Output a random unary string code-golf random Your task is simple: output the letter x a random number of times. Every possible length of xs must have a non-zero probability of being output. Of course, there must be some lengths whose probabilities tend to \$ 0 \$, in order for the total probabil...
