11>extraNumber

You're given three integers, a, b and c. It is guaranteed that two of these integers are equal to each other. What is the value of the third integer? Example For a = 2, b = 7 and c = 2, the output should be extraNumber(a, b, c) = 7. The two equal numbers are a and c. The third number (b) equals 7, which is the answer.

return a == b ? c : a == c ? b : a;
