At todays C++ meetup I was told a programming quiz:
Given the digits 1-9 (in that order), you can combine them with either '+', '-' or nothing.
Now find all of these mathematical terms, that evaluate to 100.
You can use any programming language and library you like and you have 1 hour to complete the task.
Expressions that evaluate to 100
Then I came up with a solution in #bash that took me ~5 minutes to write but with an execution time of 20s.
Generalistic and moderated instance.
