![1. Suppose we have a 2-player zero-sum game where the strategy set of the row player
(resp. the column player) is R = {₁,..., rk} (resp. C = {C₁,..., ce}) and where the
payoff matrix is A (ai). If (r₁, c₁) and (r2, C₂) are both Nash equilibria, show that
they have the same payoff (i.e. a11 a22). [Do this directly using the definitions
