find the difference between the greatest and theleast 6digit numbers formed by 0 and the first 5 odd numbers.

On the assumption that the smaller number cannot start with zero, the greatest difference is:
975310  103579 = ?
I made the first number as large as possible and the second the smallest possible using the given digits.
You can find the numbers that give minimum difference by sing similar logic.
For the minimum difference, you can chose the same number twice and get zero.
