A logic problem by I'm a MALAYSIAN!

Logic Level 2

All of the digits from 0 through 9 are used to create two 5-digit positive integers, and then the two numbers are subtracted to find their positive difference: 7291054836=18074.72910 - 54836 = {\color{#D61F06}18074}. What's the smallest positive difference we can get this way?
