/Upside-Down

An upside-down number is an integer where the ith digit from the left plus the ith digit from the right is always equal to 10. For example 13579 is an upside-down number since 1+9 = 10, 3+7 = 10 and (since 5 is both the 3rd digit from the left and from the right) 5+5"="10. Write a program to determine the nth upside-down number (in numerical order).
