odd incrementing sequence

Given a sequence of positive integers of length N (not greater than 500), take out all odd numbers and output them in ascending order.
enter

2 lines in total:

Line 1 N;

Line 2 contains N positive integers separated by spaces. output
Odd sequence of output in ascending order, separated by commas.
The data is guaranteed to have at least one odd number.
Sample input
10
1 3 2 6 5 4 9 8 7 10

Sample output
1,3,5,7,9
