 Question
Most people know that on this site there are some puzzles that contain the bitwise OR operator. Well, would it be possible to also include the bitwise AND operator? (Which outputs a 1 if both inputs are 1, but a 0 otherwise)

For example, 8 AND 5 would be 0 because
1000
0101
0000
but 7 AND 5 would be 5 because
111
101
101

(hopefully this makes sense [unsure] )

I understand what you mean. Beaker, are you familiar with the bitwise OR operator? If not, you might want to read up a bit on Wikipedia: https://en.wikipedia.org/wiki/Bitwise_operation

Sounds like an interesting idea: I think such an operator will give enough information to be useful, yet is complex enough to make things difficult.

It's a logical operator not more difficult than Bitwise OR.

Perhaps you may start with this puzzle (I had not big successs when I proposed that in 2011):

Because from a "coding perspective" such an operator is almost the same,
it wouldn't be difficult to create such puzzles.

(or puzzles with other logical operators, like XOR, NOR, ...)
