What's the solution in Julia?

I first did something with findfirst, which needed some bounds checks. Then I saw another answer and they used searchsortedfirst which is just it ... Even the documentation reads like the problem description

Ah so the library is just made for problems like this. Who would have thought :)

Naahh… searchsortedfirst is simply faster than other search algorithms (in this specific case). Extremely useful in many applications.It ist there because Julia cares about efficiency

This helped me realize how much this aligns with my problems (and I guess the spirit of this test problem). Sometimes you have special knowledge of your data and can use much more efficient functions that are just there in Julia.
