Your Task
You will write a program or function to return a truthy value if the integer inputted to it is a square repdigit, and a falsy value if it is not. A repdigit is an integer that contains only one digit. For the purpose of this challenge, a square repdigit is a repdigit that is the squa...

Given an input integer n, draw a number snake, that is, a grid measuring n x n consisting of the numbers 1 through n^2 that are wound around each other in the following fashion:
Input n = 3:
7 8 9
6 1 2
5 4 3
Input n = 5:
21 22 23 24 25
20 7 8 9 10
19 6 1 2 11
18 5 4 3 12
17 16 15 1...

Me thinks there aren't enough easy questions on here that beginners can attempt!
The challenge: Given a random input string of 1's and 0's such as:
10101110101010010100010001010110101001010
Write the shortest code that outputs the inverse like so:
01010001010101101011101110101001010110101

Your job is to output the html of the current version (at the time of this writing) of the Wikipedia page for Kolmogorov complexity: https://en.wikipedia.org/w/index.php?title=Kolmogorov_complexity&oldid=781950121&action=raw (backup)
This is code-golf, so the shortest code wins.
You should code a piece of code that looks like it outputs the language name but actually outputs the name reversed.
E.g. a Python program should look like it outputs Python but should actually output nohtyP.

My first answer!
using System;s=>{var r=new Random();for(var i=2;r.Next(i++)>0;)Console.Write(s+" ");}
Previous attempt (I liked that goto):
using System;s=>{var i=2;var r=new Random();a:if(r.Next(i++)>0){Console.Write(s+" ");goto a;}}
Ungolfed:
using System;
class P
{

So I had an idea to make a challenge where users have to make a regex expression, based on what I give them. Example:
test2 FIND
test3 FIND
test SKIP
Then they just answer with the shortest expression they can, but they don't have to use an actual language, just plain regex. Like for this chal...
