Tracing

Trace manually these program pieces.

1. a = 5
   b = 13
   c = a+b
   a = a-b
   b = b-2*a+ c
   c = round(10/3, 2)
   

2. a = -5.3
   b = int(a)
   b = float(b)
   a = a-b
   b = str(b)
   

3. x = 3
   y = 4
   a = x > y
   b = a and x < y
   a = a or x >= y
   b = a and b
   a = a or False
   b = (a and False) or (b or a)
   

4. Trace the previous program piece replacing the two first assignments by:

   x = 4
   y = 3
   

5. Trace the previous program piece replacing the two first assignments by:

   x = 4
   y = x
