Darshan Gajara 
Does this work??
Hey Aarthi, haven’t tried it for a while, but used to work when I wrote it.
Hello Mr. Gajara,
Your code is simple and easily understandable. One small suggestion would be to get the random numbers from the users and then compute Xa and Xb, and from there, it is perfect. Thank you for your code
Hey Alexandria,
Glad that it helps. Good suggestion, I had written this some 4 years back, haven’t been doing much coding since past 2 years. Could you just add the modification in the comment?
Also, I had prefer Darshan š
