Accept the indexing pool from which numbers are selected and returned.
Correct its format to suit the current NumberSelector algorithms.
Moving all of the invalid negative-ones (-1) to the left of the current valid indices works for most selectors.
The selectionIndex is set to the first valid number available from the left.
The ret index is set to index zero.

Give a number back to a specific collection following the principles of this selector.
The number is always returned to a "used" index position near the front of the array.
Give a number back to a specific collection following the principles of this selector.
The number is always returned to a "used" index position near the front of the array.
It locates this position by incrementally traversing the Array behind the position used in Get.
Asides from selection, a disorderly reinsertion of numbers back into the pool is also a source of randomness.

Get a pseudorandom number from a pool of numbers. The contained logic is similar to
RandomSequenceSelector. It is not reliant of a shrinking pool that composes into some sequence of all the numbers, however; the numbers are re-introduced to the selection as long as the pool is used. This allows for the sequence to contain repeat numbers far before ever visiting all of the numbers once.During the selection process:
The index is the position from where the selection begins, and the end of the
Arrayis where the selection ends. Once a position between those two indices is selected, that number is extracted. The number at the start position is swapped into the position where the selection number was extracted. The start position is then set to an invalid number, and the start index is advanced. Repeat next request.During the return process:
The returned number is added to the input
Arrayat the position just before the current selection position. The selection index is then reversedback to re-include the returned number. The normal return index is not used in this algorithm.RandomSequenceSelector
