I tested the code. It compiles and runs just fine. I compared the checksum of the output from both Rust and this version, they are identical:

md5 5b185f9a67a426baf78aa3bbb5baf8df out_rust

md5 5b185f9a67a426baf78aa3bbb5baf8df out_ada

On top of that, I got this:

Rust:

real 0m0.702s

user 0m0.693s

sys 0m0.007s

Ada:

real 0m0.708s

user 0m0.706s

sys 0m0.000s

Why don't you use this version instead? The output is correct and identical to Rust's, and the performance is significantly better: just as fast as C and Rust, as expected.

Thanks for letting us know about its existence!

I tested it with N = 10000. I see the issue now though.

Edit: I do not understand your reaction to me thanking you for bringing my (and possibly other people's) attention to the other implementation. It was genuine.

Okay, my mistake then. :)

On the benchmarks game website anything underlined is a URL.

On the faster/ada.html page there's a link "all other Ada 2012 GNAT programs & measurements".

On the performance/pidigits.html there's a link "Ada 2012 GNAT #2".

Okay, thank you for the steps. I have to admit I completely missed it at first.

> I compared the checksum

At what N?

> The output is correct

Nope. diff

Here is the code that should solve your output issue: https://slexy.org/view/s21DoMQaHF

Thanks, done.

No worries. I got rid of the unnecessary `range' in the last version, but it does not matter much anyway.

My guess is that the Ada regex-redux #6 program is also easily fixable:

:and there's a working Ada regex-redux #5 program:
