Question

Mathematics

Good afternoon, actually the question is in the header. As far as I understand, you need to check each digit

Answer 1

You're right.

Answer 2

yes, you need to check every digit in the number

Answer 3

The easiest way, in my opinion, is to translate the number into a string and work with characters. Find the minimum digit by enumeration, remember its position in the line, copy the rest of the line after the minimum digit to the position of the minimum digit.

Answer 4

Try to find the minimum number and compare all numbers with it and delete it.
