Function `std.algorithm.sorting.nthPermutationImpl`


						
				bool nthPermutationImpl(Range)(
				
  auto ref Range range,
				
  ulong perm
				

				)
				

				if (isRandomAccessRange!Range && hasLength!Range);

Returns

true in case the permutation worked, false in case perm had more digits in the factorial number system than range had elements. This case must not occur as this would lead to out of range accesses.

Example

auto src = [0, 1, 2, 3, 4, 5, 6];
auto rslt = [4, 0, 6, 2, 1, 3, 5];

bool worked = nthPermutationImpl(src, 2982);
assert(worked);
writeln(src); // rslt
