Which year is it ?

Computer Science Level 1

2016 O R 2017 \large {{2016}} \, \, {{OR}} \, \, \large{{2017}}

For any two non-negative integers A A and B B , A O R B A \, OR \, B is an integer obtained by taking O R OR (a logical operator) of the respective bits (with same significance) in the binary representation of both the numbers.

What number do you get from the given expression?

Here is a similar one.


The answer is 2017.

( 2016 ) 10 = ( 11111100000 ) 2 \left( 2016 \right)_{10} = \left( 11111100000 \right)_2 a n d and ( 2017 ) 10 = ( 11111100001 ) 2 \left( 2017 \right)_{10} = \left( 11111100001 \right)_2 t h e r e f o r e therefore ( 2016 ) 10 O R ( 2017 ) 10 = ( 11111100001 ) 2 = ( 2017 ) 10 \left( 2016 \right)_{10} \, OR \, \left( 2017 \right)_{10} = \left( 11111100001 \right)_2 =\left( 2017 \right)_{10}

Actually, you have take OR of the respective bits in the binary representation of both 2016 and 2017
