I'm currently creating an experimental programming language for fun and educational purpose and in search for some tasks beyond the classical "Hello, World!"-program.
I've already come up with these ideas:
Print out the program's input
Calculator
Generate Prime numbers, Fibonacci series
What other interesting programming problems do you have for me to test?
It would be good if they required the language to solve a broad spectrum of task, take prime numbers for example: You need variables, increment them, divide them, perform actions under certain conditions, etc.
