Order of Execution
In a recursive function, the position in which additional statements (i.e., statements other than the recursive call itself) are placed is important. In the simple case of a function calling itself only once, a statement placed before the recursive call will be executed first in the outermost stack frame, while a statement placed after the recursive call will be executed first in the innermost stack frame. Consider this example:

Famous quotes containing the words order and/or execution:
“Out of the slimy mud of words, out of the sleet and hail of verbal imprecisions,

There springs the perfect order of speech, and the beauty of incantation.”
—T.S. (Thomas Stearns)
“If I were asked to chose between execution and life in prison I would, of course, chose the latter. It’s better to live somehow than not at all.”
—Anton Pavlovich Chekhov (1860–1904)
