Returns the position immediately before the given index.
func index(before i: Self.Index) -> Self.Index A valid index of the collection. i must be greater than startIndex.
The index value immediately before i.

func formIndex(before i: inout Self.Index) Replaces the given index with its predecessor.
func index(_ i: Self.Index, offsetBy distance: Int) -> Self.Index Returns an index that is the specified distance from the given index.
func index(_ i: Self.Index, offsetBy distance: Int, limitedBy limit: Self.Index) -> Self.Index? Returns an index that is the specified distance from the given index, unless that distance is beyond a given limiting index.
