Hello all,
A couple of queries. The first I'm sure has been asked/answered
definitively before, but a search doesn't bring anything up: is
it possible to foreach() over every element of a multidimensional
array, i.e. something like,
int[3][4][5] a;
foreach(ref int n; a)
n = uniform!"[]"(0, 1);
... or is it necessary to do a separate foreach over each
dimension?
The second query relates to slices. Suppose I have an N*M 2d
array (let's call it a), and a 1d array of length N (let's call
it s) whose elements are unsigned integers whose values fall in
[0, M). What I'd like is to take a slice of a such that I get
out a 1d array of length N such that the i'th element corresponds
to a[s[i]].
Is this possible? And if so, how is it achieved?
Thanks and best wishes,
-- Joe
