The Mad-Titan has ordered Ebony Maw to take his ship to destroy the Earth. The ship is equipped with 3 Laser Guns each of different type. Iron-Man, Vision, and War-Machine are searching for the weak spot to destroy them. Each Laser Gun denotes a non-negative inte- ger, all 3 integers are different. Each of the heroes is given a gun of their own and each of them fires at one of the rival guns of the ship in one single round. The points are awarded depending upon the integer corresponding to the gun he shoots in that round. Friday, an AI created by Tony helps to distribute the Laser Gun between three of them before each round. After a number of rounds `(ge2)` Iron-Man has 20 points, Vision has 10 and War-Machine has 9. We know that in the last round Vision has hit the gun corresponding to maximum integer.
If the points assigned to the guns are x, y and z (xgtygtz), Then find out which of the three has fired the Laser Gun corresponding to the integer value y in the first round and z in second round?
