Many times I have to get statistical info which is simply
compute statistics on a data set that may be generating or
already generated.
The code usually is
M = max(M, v);
m = min(m, v);
but other things like standard deviation, mean, etc might need
to be computed.
This may need to be done on several data sets simultaneously.
is there any way that one could just compute them in one line
that is efficient, probably using ranges? I'd like to avoid
having to loop through a data set multiple times as it would be
quite inefficient.
You can use `std.algorithm.fold` to compute multiple results in a
single pass:
auto stats = v.fold!(max, min);
M = stats[0];
m = stats[1];
