# Task

**_Given_** a **_list of digits_**, *return the **_smallest number_** that could be formed from these digits, using the digits only once (ignore duplicates).* 
___

# Notes:

* Only **_positive integers_** *will be passed to the function (> 0 ), no negatives or zeros.*
___
# Input >> Output Examples 

```
minValue ({1, 3, 1})  ==> return (13)
```
## Explanation:
**_(13)_** *is the minimum number could be formed from* **_{1, 3, 1}_** , *Without duplications*  
___
```
minValue({5, 7, 5, 9, 7})  ==> return (579)
```
## Explanation:
**_(579)_** *is the minimum number could be formed from* **_{5, 7, 5, 9, 7}_** , *Without duplications* 
___

```
minValue({1, 9, 3, 1, 7, 4, 6, 6, 7}) return  ==> (134679)
