The number may only use the specified digits, it does not have to use them. Read the question.

why they stop at 110 ?
my english is not very good please explain more

The goal is to find "the smallest strictly positive multiple of N that has no other digits"

So why stop at the smallest? Because that's what you're trying to find.

smallest is the key as @cire pointed out. This means there will only be one smallest, so find it

[kulkarnisr]

In the above ex,
N = 22
M = 3

and M1, M2, M3 = { 7, 0, 1}

22*2 = 44
22*3 = 66
22*4 = 88

// Smallest multiple using the given no's (M1,..)
22*5 = 110

@kulkarnisr
how to understand "the smallest strictly positive multiple of N that has no other digits"? what's the meaning of "22*2 = 44,22 *3 = 66, 22 * 4 = 88"?
and then how to get the answer" 22*5 =110"?
