Write a code for the function main, that does the steps below.

Make sure to use the exact variables names listed:

uses a while loop which runs as long as a variable named Running stores a true value $-$

think about initialization

inside the while loop, get three integer numbers $n1,n2$ and $n3$ from the user $-$ use those

variable names.

if passing those inputs in that order to the function of the previous question results in a

value that is not $-1,$ then add that value to a running sum.

Think about what is need to use a running sum.

Make sure not to call the function of the previous question twice and to save its result in

a variable.

Otherwise make the loop stop by setting the value of Running without using break.

After the loop stops, check the running sum, if it is more than $0,$ print it; if it is less than

$0,$ print an error message, otherwise if it is $0,$ print "Wow".

All variables must be initialized.

Call main at the end.

Use conversion or casting functions as needed.
