random-access range whose elements are to be shuffled
The shuffled random-access range.
auto rnd = MinstdRand0(42); auto arr = [1, 2, 3, 4, 5].randomShuffle(rnd); version (D_LP64) // https://issues.dlang.org/show_bug.cgi?id=15147 assert(arr == [3, 5, 2, 4, 1]);
Shuffles elements of r using gen as a shuffler. r must be a random-access range with length. If no RNG is specified, rndGen will be used.
