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:
“We do not live to think, but, on the contrary, we think in order that we may succeed in surviving.”
—José Ortega Y Gasset (1883–1955)
“My weakness has always been to prefer the large intention of an unskilful artist to the trivial intention of an accomplished one: in other words, I am more interested in the high ideas of a feeble executant than in the high execution of a feeble thinker.”
—Thomas Hardy (1840–1928)
