Assume a sorted character array of size n = 26. It contains all the capital letters, i.e, 'A' to 'Z', in increasing order as array elements. Let the search key be equal to 'X' (upper case letter). What is the last letter that will be compared with the search key using a binary search algorithm? You may choose not to enclose your answer within a pair of single quotes.
