Devu and an Array

Devu has an array A consisting of N positive integers. He would like to perform following operation on array. - Pick some two elements a, b in the array (a could be same as b, but their corresponding indices in the array should not be same). Remove both the elements a and b and instead add a number x such that x lies between min(a, b) and max(a, b), both inclusive, (i.e. min(a, b) ≤ x ≤ max(a, b)
