An algorithm for searching a large sorted array for a specific value x compares every third item in the array to x until it finds one that is greater than or equal to x. When a larger value is found, the algorithm compares x to the previous two items. If the array is sorted in increasing order, which of the following de- scribes all cases when this algorithm uses fewer comparisons to find x than would a binary search? (A) It will never use fewer comparisons. (B) When x is in the middle position of the array (C) When x is very close to the beginning of the array (D) When x is very close to the end of the array (E) When x is not in the array
