101 How to find the step response of discrete time system $ H(z)$ and plot on top of the step response of its continuous time approxmation $ H(s)$?

Plot the step response of $ H(z)=z/(z^2-1.4 z+0.5)$ and using sampling period of $ T=0.5$ find continuous time approximation using zero order hold and show the step response of the system and compare both responses.
