Returns the inner function to F1 (if inner parentheses, the inner function is executed first) #   then the F1 function only wants to inner the function. If you call F1, execute the inner function, example * @ + function name # function: # 1. Automate the execution of the outer function and pass the following function name F1 as a parameter.
