Reverse that. 4 and 9 are factors of 72.
Add -3 to 9 because 9+(-3) = 6 Alternatively add s to the Roman numeral of ix which is 9 which then becomes six.
main() { int no,reverse=0,digit; scanf("%d",no); for( ;no>0; ) { digit=no%10; reverse=reverse*10 + digit; no=no/10; } printf("%d",reverse); }
The difference between a number and its reverse must be divisible by 9. 42 is NOT divisible by 9. There is, therefore, no such number.
