ReverseApplied

ReverseApplied[f] represents a form of f that takes arguments in reverse order so that ReverseApplied[f][x1, ..., xn] is equivalent to f[xn, ..., x1].

• ReverseApplied[f, n] represents a form of f that reverses the first n arguments before evaluation.

Examples

Reverse all arguments:

ReverseApplied[Divide][2, 10]
(* 5 *)

Reverse first 2 arguments:

ReverseApplied[f, 2][a, b, c, d]
(* f[b, a, c, d] *)

Use with Subtract:

ReverseApplied[Subtract][3, 10]
(* 7 *)
