Consider the following program which includes functions thatcall other functions in a confusing way:
def a(x): return xdef b(y): return a(y) + a(1)def c(z): if z < 3: return a(b(a(b(z)))) else: return b(z) – a(2)print(____(0)) # Should print “1”print(____(0)) # Should print “2”print(____(4)) # Should print “3”print(____(4)) # Should print “4”
At the end, the program prints out four numbers by calling oneof the functions defined above. The goal is two call functions inthe right order
