int unordered Search (const T a[], unsigned n, const T& x) // Look for x within an unsorted array a, containing n items. // Return the position where found, or -1 if not found. { int i; for (i = 0; ((i < n) && (a[i] != x)); i++) ; if (i >= n) i = -1; return i; } Assume that: exactly half of the searches are for "x" values that really are in the array "a", and for those searches, each element of "a" is equally likely to be searched for. What is the average case complexity of unordered Search for this input distribution?

Specifically, assume that: we only search for "x" values that really are in the array "a", and the probability of any particular search being for the element a[i] is c/(2). What is the average case complexity of unordered Search for this input distribution? (Show your work).
