Was solving the GO 2019 pdf when I encountered this question asked in TIFR 2017. Although I have understood this question, I have one doubt- It is mentioned in the question that for a 3-bit number, the ordering (000, 100, 101, 111, 110, 010, 011, 001) is one of the possible Gray codes. Then, how many such orders are there for an n-bit number?

Let the valid moves along a staircase be U (one step up) and D (one step down). For example, the string s = UUDU represents the sequence of moves as two steps up, then one step down, and then again one step up. Suppose a person is initially at the base of the ... to the base of the staircase after the final step. (a) Show that L is not regular. (b) Write a context free grammar for accepting L.

Let $a_{n−1}a_{n−2}...a_0$ and $b_{n−1}b_{n−2}...b_0$ denote the $2's$ complement representation of two integers $A$ and $B$ respectively. Addition of $A$ and $B$ yields a sum $S=s_{n−1}s_{n−2}...s_0.$ The outgoing carry generated at the most significant bit ... $\oplus$ denotes the Boolean XOR operation. You may use the Boolean identity: $X+Y=X⊕Y⊕(XY)$ to prove your result.
