Numbers Game

Kirito loves games, especially those involving odd numbers. On a rainy day, when he couldn't go outside play with his friends, he decided to play alone. He wrote random numbers in pieces of papers and put them down on a bag. Then he mixed them, took 2 numbers (x,y) and asked himself: "what is the sum of the decimal digits of the odd numbers in the range [min(x,y),max(x,y)] (including the boundaries)?”

Now your task is to help Kirito in his game.
