Add checkInRange in ObjectUtil (#10668)

Browse Source 
Motivation:
We check lots of numbers if it lies in a range. So it's better to add a method in `ObjectUtil` to check if a number lies inside a range.

Modification:
Added Range check method.

Result:
A faster and better way to check if a number lies inside a range.
