One quick question. Why did u put "number/2" in rangeclosed Method... I did not understand that because of 7, range would be 2 to 3.5 ? Please suggest...

[@_rishabh]

Hi Praveen,
number/2 will return 3 if 7 is passed as parameter (as it is "int"),
Logic of checking prime number is basically if we get a number we divide it by 2,
for 7 it will be 7/2 =3
now we will divide 7 by each number starting from 2 ( in this case 2 and 3),
if it gets completely divided by any number then we will simply say it is not prime else prime.
Hope it clears your confusion.
