Gray Code (Self Doubt)
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 ... base of the staircase after the final step. (a) Show that L is not regular. (b) Write a context free grammar for accepting L.
