The payoff of a leveraged European call option is given below.

C_L (T) = mS(T) - K if S(T) > K and = 0 if S(T) < K, where K is the strike price and m is a constant.

The payoff of a digital call option is:

C_D (T) = 1 if S(T) > K and = 0 if S(T) < K

Replicate the payoff of the leveraged option at date zero using a combination of standard and digital European call options both with strike price K.
