In the A5/1 algorithm. Suppose that, after a particular step, the values in the registers are

X = (x₀, x₁, , x₁₈) = (1010101010101010100)

Y = (y₀, y₁, , y₂₁) = (1100110011001100110010)

Z = (z₀, z₁, , z₂₂) = (11100011100011100011100)

List the next 3 keystream bits and give the contents of X, Y, and Z.
