Question $3$

Consider the following sets of secret operations. For each set of operations, determine if they are masking ON or masking OFF, and determine the masking pattern for each set of operations.

Note that each set of operations contains TWO groups of input and output patterns.

Use the TWO groups of input and output patterns to determine the masking pattern used in this set.

When fill the masking pattern, use $x($lower$-$case English letter$)$ to indicate a bit can be either $0$ or $1.$ See the following example.

$1$x$01$ means both $1101$ and $1001$ can be used as the masking pattern,

$11$xx mean the masking pattern can be one of $1100,1101,1110,$ and $1111.$
