and we set C equal to AXORB, and then take CXORB: we get AXORBXORB, which essentially either flips every bit of A twice, or never flips the bit, so we just get back A. (We can also think of BXORB as cancelling out.) As an exercise, can we think of a way to use this to ...

Bit Twiddling was used in earlier days for efficiency. It is a technique used for bit manipulation. Java bitwise and bit shift operators such as NOT, AND, OR, XOR, LEFT-SHIFT, RIGHT-SHIFT, UNSIGNED-RIGHT-SHIFT can be used to perform operations such as multiply or divide integers, test fo...
How we built it We utilized MongoDB Stitch to build the backend side of the application because it helped us to focus more on working on the features of the appliction rather than on managing data manipulation code, service integration, and backend infrastructure. We made use of React J...
