I think this is not the right approach for you to solve UVA problems...you will have to put in ur time to solve ...thats the only way in which you can improve. I strongly urge the group to stop sending accepted solutions. regards, Pradeep On 6/10/07, Vishal <[EMAIL PROTECTED]> wrote: > > if ( n <

if ( n <= 9 ) return (10+n); ret = 0; while (n>9) { found = false; for ( i = 9 to 2 ) if (n%i == 0) { ret = ret * 10 + i; n /= i; found = true; } if ( !found ) { print( "Not possible"); return; } } Now sort the digits of ret and return. However this will work for sm

Hi everbody , i am trying to solve this problem http://acm.uva.es/p/v105/10527.html but i am not getting any efficient algorithm . One algorithm i applied while(n>9) for i=2 to 9 if(n%i=0)//then i is factor of n and may be a digit in the number store i for further processing n=n
