Description
Sorts the given T2DPointArray ATPA by the distance of the first point in every non-empty subarray to the TPoint given in Point using the fast ShellSort algorithm. Empty subarrays are placed at the start of the array.
Example
var ATPA: T2DPointArray; i: Integer; begin SetLength(ATPA, 3); ATPA[0] := [Point(1, 6), Point(5, 4), Point(1, 5)]; ATPA[1] := [Point(1, 1), Point(2, 2)]; ATPA[2] := [Point(5, 10)]; SortATPAByFirstEx(ATPA, Point(5, 5)); for i := 0 to High(ATPA) do WriteLn(TPAToStr(ATPA[i])); end.
Output:
(1,6);(5,4);(1,5) (5,10) (1,1);(2,2)
