Question 1 Trace (by hand) execution of the following program, showing the values of the variables, in the correct scope(s), as they change, and also giving the output. Include line numbers in your trace as usual, noting the following special cases: For a line where a method call is executed, express the line number as method_call_line_number/method_header_line_number. For example, for the method call on Line 5, you would enter 5/9 in the Line Number column and show the value of any variables that are affected by the call to the method. For a line containing a return from a method call, express the line number as follows return_line_number/original_method_call_line_number. For example, for the return on Line 13, you would enter 11/5 in the Line Number column and show the value of any variables that are affected by the return from the method. Use the following input values, in this order (you may not need all values): 3 3 15 4 7 def main() : #Line 1 m = int(input ("Enter an integer number: ")) #Line 2 for i in range (m): #Line 3 n = input ("Enter an integer number: ") #Line 4 o = isValid (n) #Line 5 if o: #Line 6 printP(n,m) #Line 7 else: print("Please enter a valid integer value:") #Line 8 def isValid (m): #Line 9 if int (m) >0 and int (m)
