PROGRAMMING:Sfy finding the product of odd numbers
Before will calculate the largest even number, find out the odd number for you certainly not difficult, come to calculate the odd number product. I'll give you n integers to multiply all the odd numbers in them.
###Input format:
Each test instance occupies a row, and the first number of each row is n, which means that there are n data in this group, followed by N integers,
You can assume that there must be at least one odd number for each set of data.
###Output format:
Output the product of all odd numbers in each group. For test cases, output one line.
###Input example:
Here is a set of inputs. For example:
```in
3 1 2 3
4 2 3 4 5
```
###Output example:
The corresponding output is given here. For example:
```out
three
fifteen
```
