# Daily Challenge #160 - Expression Matters

### dev.to staff ・1 min read

## Task

Given three integers `a ,b ,c`

, return the largest number obtained after inserting the following operators and brackets: `+, *, ().`

*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`

So the maximum value that you can obtain is 9.

## Notes

- 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 cannot get expression
`(1 + 3) * 2 = 8`

.

*Input >> Output Examples*:

`expressionsMatter(1,2,3) ==> return 9`

*Explanation*:

After placing signs and brackets, the maximum value obtained from the expression `(1+2) * 3 = 9`

.

`expressionsMatter(1,1,1)`

==> return 3

*Explanation*:

After placing signs, the Maximum value obtained from the expression is `1 + 1 + 1 = 3`

.

`expressionsMatter(9,1,1)`

==> return 18

*Explanation*:

After placing signs and brackets, the maximum value obtained from the expression is `9 * (1+1) = 18`
