Proposed question: My fifth-grade daughter is learning about codes and ciphers. She has reached the point of decoding a cyphertext that has been encoded with the Caesar cypher even where the offset is not provided in advance.
Without computers this can be time-consuming, especially for long bloc...
Word Game KotH king-of-the-hill
First of all, I don't know what this game is called (or if it even has a name), but it's a modification of a game I've played a few times on road trips, especially with my family. I'll be thinking of a better name.
Any suggestions at all are very welcome.
How It...
Objective
Given a grid of numbers, fill in the inequalities.
Assumptions
The number of columns and rows in the grid are equal.
The maximum size of the grid is 12x12.
The grid only consists of integers 0-9.
The output may contain a trailing newline.
The input is exactly as written below, includ...
This is a simple challenge: Given an input string only containing the characters A-Z, a-z, and spaces, remove all occurrences of the uppercase and lowercase versions of the first character of the string (if the first character is A remove all As and as, if the first character is (space) remove al...
Ouroboros, 82
Ouroboros is an esolang I designed this week. Time to take it for a spin!
i.1+!57*(\m1(M\1).96>.@32*-.80=\.78=3*\.66=3*\.82=5*\81=9*++++\2*1\-*+

Each line of single-char commands1 represents an ouroboros snake, wherein execution proceeds from head (start) to tail (en...

ncr.... but i've been getting some kind of error... it'd be helpful if
someone finds out that for me and help me resolve it

King of the Sausage
This is just a rough idea that I think would be fun, but as I do not have the time to do it right now, feel free to adopt (just let us know in order to avoid collisions.)
I believe I saw this 'game' in a tv show once: Two competitors are each given a sausage of equal weight....
Write a program or function that outputs/returns the first 10000 prime-indexed prime numbers.
If we call the nth prime p(n), this list is
3, 5, 11, 17, 31, 41, 59 ... 1366661
because
p(p(1)) = p(2) = 3
p(p(2)) = p(3) = 5
p(p(3)) = p(5) = 11
p(p(4)) = p(7) = 17
...
p(p(10000)) = p(104729) = 1...
Challenge
Given a list of numbers, calculate the population standard deviation of the list.
Use the following equation to calculate population standard deviation:
Input
The input will a list of integers in any format (list, string, etc.). Some examples:
56,54,89,87
67,54,86,67
The number...
Per recommendation I am reposting this from Stack Overflow.
Recently I have been thinking about following issue.
Consider a code for a standard "Hello world!" program:
main()
{
printf("Hello World");
}
Now almost any change in this code will make it completely useless, in fact almost ev...
