The story definitely reminds one of “Birth’ by A. J. Cronin. There is a striking similarity between both the stories. Both revolve around doctors who try their level best to save the lives of nearly dead human beings. In the story ‘Birth’, Dr Andrew saves the life of an almost still born baby boy with a lot of effort, while ‘The Enemy’ deals with the story of Dr Sadao who saves an American soldier from the enemy troops during the times of war. Both the stories deal with humanity, love, affection, selflessness and a strong sense of duty.
A school is organizing a debate competition with participants as speakers and judges. $ S = \{S_1, S_2, S_3, S_4\} $ where $ S = \{S_1, S_2, S_3, S_4\} $ represents the set of speakers. The judges are represented by the set: $ J = \{J_1, J_2, J_3\} $ where $ J = \{J_1, J_2, J_3\} $ represents the set of judges. Each speaker can be assigned only one judge. Let $ R $ be a relation from set $ S $ to $ J $ defined as: $ R = \{(x, y) : \text{speaker } x \text{ is judged by judge } y, x \in S, y \in J\} $.
