Question 965250
I am a 4-digit number and if my digits are reversed then I become a 3-digit
number. What is the digit in my one's place?
<pre>
For instance, if it were 6470, and we reversed the digits,
we would have 0746, which is really 746, a 3-digit number,
so the last digit (1's place digit) must be 0.
