The game of Chango is a game where two people play against each other, one of them wins and the other loses, i.e., there are no drawn Chango games. $12$ players participated in a Chango championship. They were divided into four groups: Group $\text{A}$ consisted of Aruna, Azul, and Arif; Group $\text{B}$ consisted Brinda, Brij, and Biju;  Group $\text{C}$ consisted of Chitra, Chetan, and Chhavi; and Group $\text{D}$ consisted of Dipen, Donna, and Deb.

Players within each group had a distinct rank going into the championship. The players have $\text{NOT}$ been listed necessarily according to their ranks. In the group stage of the game, the second and third ranked players play against each other, and the winner of that game plays against the first ranked player of the group. The winner of this second game is considered as the winner of the group and enters a semi-final.

The winners from Groups $\text{A}$ and $\text{B}$ play against each other in one semi-final, while the winners from Groups $\text{C}$ and $\text{D}$ play against each other in the other semi-final. The winners of the two semi-finals play against each other in the final to decide the winner of the championship.

It is known that:

1. Chitra did not win the championship.
2. Aruna did not play against Arif. Brij did not play against Brinda.
3. Aruna, Biju, Chitra, and Dipen played three games each, Azul and Chetan played two games each, and the remaining players played one game each.
