Answer 1

Num%10 will give you reminder (the last digit). Num/10 give you eliminated last digit. So loop this will give you iterating to individual digits. You can find by if-Else which one is greater.
Now again loop through, you can remove big number.

Answer 2

And how I eliminate the greater digit?

Answer 3

If you try finding big number that way, you can get idea to eliminate it similar way..
By removed digits, you can form the same number by adding to new variable. In that process ,you can skip adding big number. Hope you can find , better solution once it worked that way...
Adding if r is reminder of original Number N, then r=N%10; new1=r*10+new1; will form new number...

And how can I rebuild the number in the same while loop?
