[ ASSIGNMENT: ] Expressions Matter

Question

TASK : Given three integers a, b, c,
return the largest number obtained after inserting the following operators and brackets  +,  *,  ( )

For Example : :

1. expressionsMatter(1,2,3) --> return 9
After placing signs and brackets, the Maximum value obtained from the expression is (1+2) * 3 = 9

2. expressionsMatter(9,1,1) --> return 18
After placing signs and brackets, the Maximum value obtained from the expression is 9 * (1+1) = 18

Answer 1

Consider an Example :
With the numbers are 1, 2 and 3, here are
some ways of placing signs and brackets

1 * (2+3) = 5
1 * 2 * 3 = 6
1 + 2 * 3 = 7
(1+2) * 3 = 9
the Maximum value, 
that you can obtain is 9

NOTE :
- The numbers are always positive.
- The numbers are in the range
 (1 ≤ a, b, c ≤ 10).
- You can use the same operation more
than once.
- It's not necessary to place all the signs
and brackets.
- Repetition in numbers may occur.
- You cannot swap the operands.
For instance, in the given example you can't get expression (1+3) * 2 = 8

Answer 12

My code

(Written by language python)

def d2(x1,x2):
if x1>1 and x2>1:
return x1*x2
else:
return x1+x2

def d3(x,y,z):

return max(d2(x,d2(y,z)),
d2(y,d2(x,z)),
d2(z,d2(x,y)),
x*y*z,
x+y+z
)
a,b,c=eval(input()),eval(input()),\
eval(input())
print(d3(a,b,c))
