Answer 3

Donna in front of the no. itself ..

Lyk for ex. in 230769 ,
if 9 is taken out n put in front , then the new no. is 923076 .

And , 923076 = 230769 × 4 .

Answer 4

Answer 6

the for loop is a infinite one in fact

for(long=1; i<=0; i++)

never ends.
Try with:

for(long i=0; i<=1000; i++)

or something like this.

Answer 7

In CP it works only with i<=70000, you could try in your computer....
