1. Implement the A5/1 algorithm in C/C++. Suppose that, after a particular step, the values in the registers are
X = (x0, x1, . . . . ., x18) = (1010101010101010101)
Y = (y0, y1, . . . . ., y18, y19, y20, y21) = (1100110011001100110011)
Z = (z0, z1, . . . . ., z18, z19, z20, z21, z22) = (11100001111000011110000)
