Bitwise rotation
WebJan 24, 2024 · A bitwise rotation is like a bitwise shift, except that any bits shifted off one end are added back to the other end. For example 0b1001u << 1 would be 0b0010u, but a left rotate by 1 would result in 0b0011u instead. Implement a function that does a left rotate on a std::bitset<4>. For this one, it’s okay to use test() and set().
