sider the following code: of Progran to practice function calls and the call stack def functiona(n:int =15)> int: n= functionel print("In functiona") return n+1 det functions(n: int =10] int: n= functionc [2n] print("In functionB") return n+2 def functionc(ni int)-\$None: print("In functionc") return n+5 result = functiona(3) t1: Trace by hand the is the number output by line 17 of the code? 2: Call Stack iis part you will draw the stack after the code executes line 9. (Note: you don't have to fill in the bottom of the stack for the main code block ee first blank for each level you can put functionA, functionB, functionC, or NA (if the stack doesn't extend to that level). he second blank for each level, put in either the numerical value of n, or else NA (if the stack doesn't extend at that level). the value of n is level 4 the value of n is : level 3 the value of n is : level 2 the value of n is : level 1 in : Bottom of the stack (you don't have to fill this part in) ]: level 0
