Results for 0 is 10
For 1..9 is 1..9, it's OK.
For 128 is 2222222
Here is alg
int n;
int e=0;
int q=0;
cin>>n;
if(n==1){cout<<1;cin>>n;return 0;}
if(n==0){cout<<10;cin>>n;return 0;}
while (n>1)
{
e=0;
if(q==-1)break;
for(int i=2;i<=9;i++)
{
if((n/i)*i==n)
{
q=q*10+i;
n=n/i;
break;
}
else
{if(i==9)e=1;}
}
if (e==1)
q=-1;
}
cout<<q;
cin>>q;
return 0;
Thanks. On input 45 correct answer is 59!

sory, but why for 60 is 256? i think it's 160 1*6*0 =0;
0 != 60

Edited by author 26.08.2011 03:02 for 128 isn't 2222222 , is 882
for(int i=2;i<=9;i++)
corect is:
for(int i=9;i>=2;i--) becouse 222 is the same product like 8, 33 like 9 no for 128 minimal is 288 and not 222222 What's in this test?
Results for 0 is 10
For 1..9 is 1..9, it's OK.
For 128 is 2222222
Here is alg
int n;
int e=0;
int q=0;
cin>>n;
if(n==1){cout<<1;cin>>n;return 0;}
if(n==0){cout<<10;cin>>n;return 0;}
while (n>1)
{
e=0;
if(q==-1)break;
for(int i=2;i<=9;i++)
{
if((n/i)*i==n)
{
q=q*10+i;
n=n/i;
break;
}
else
{if(i==9)e=1;}
}
if (e==1)
q=-1;
}
cout<<q;
cin>>q;
return 0;
Thanks. |
