s="insert your numbers here" # this line not counted per the rules
n=s.split.map &:to_i
puts (n.min..n.max).select{|x|x%2==1&&!n.index(x)}*?,

Output is identical to examples in question except that it outputs a blank line for no numbers found.

),    # Extract the max and make an array A of 0 to max-1 inclusive
\(),  # Extract the min and make an array B of 0 to min inclusive
+-    # Combine B with the remaining numbers from the input and remove them from A
{1&}, # Filter A to odd numbers
','*  # Comma-separate
