- How about printing out all digits of an integer in reverse order?
- How about printing out all digits at even positions? For instance given 823456, you print out 6, 4, 2 but not 8 because 8 is the 5th digit. You see the right most digit is 0th.
- How about printing out left half of the digits? If the total number of digits is odd, you print out the smaller half.
