nificant bit and can have leading Us. (c) L3 = {w | w is a string of the form x141 X2Y2 ... XnYn for some natural number n such that if x is the integer with binary representation X1X2 ... In and y is the integer with binary representation yiy2 ... Yn then x > y}. Both x and y are presented starting from the most significant bit and can have leading Os. (d) L4 = {w w represents a possible series of flips in the game in which player 1 wins where H represents heads and T represents tails} where the game goes like this: Repeatedly flip a coin. On heads, player 1 gets a point. On tails, player 2 gets a point. A player wins (and the game ends) as soon as they are ahead by two points. nificant bit and can have leading Us.
