The General was totally governed by self absorption. He was a patient of Dr Sadao and did not trust anyone except him when it came to his health. He could not take the risk of living unprotected if the doctor was executed for treachery. He had personal assassins whom he promised to use for killing the injured soldier. But ironically, he forgot his promise to help the doctor. Humanity was not his cup of tea.
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\} $.
