Write a program with non-void version of above function and then write flow of execution for both the programs.

Q. Write a program with non-void version of above function and then write flow of execution for both the programs.

Answer :-

Non Void Version :-

def fun(x):              #1
    return (x ** 2)      #2

print (fun(4))           #3
print (fun(6))           #4
print (fun(2+1))         #5
print (fun(4-3*2))       #6
print (fun(3-2))         #7

Flow of execution :-

1 --> 3 --> 1 --> 2 --> 3 --> 4 --> 1 --> 2 --> 4 --> 5 --> 1 --> 2 --> 5 --> 6 --> 1 --> 2 --> 6 --> 7 --> 1 --> 2 --> 7

Void Version :-

def fun(x):              #1
    print (x ** 2)       #2

fun(4)                   #3
fun(6)                   #4
fun(2+1)                 #5
fun(4-3*2)               #6
fun(3-2)                 #7

Flow of execution :-

1 --> 3 --> 1 --> 2 --> 4 --> 1 --> 2 --> 5 --> 1 --> 2 --> 6 --> 1 --> 2 -->  7 --> 1 --> 2
