Explanation:
We have to round off the given population number to certain digits.
The following are the rules to round of a number:
- First identify the digit to be rounded.
- If this digit is followed by 5,6,7,8,9 then we round up the number that is increase the digit by 1 and all the numbers to right becomes zero.
