Write a simple program (as a pseudocode or any programming language) to show how one can use it to try to find the private key in ECC (having two points P and Q ). Assume the starting point on the curve is P and the public key is Q which is another point on the curve, additionally, in your pseudocode or program assume the operation "." (in some documents it is shown by "+") has been defined so you can simply apply it on two points on the curve. [4 marks] Explain in which circumstances such a program can find the private key.
