/**
 * Procedure:
 *   ith_smallest
 * Parameters:
 *   strings, an array of strings
 *   size, a positive integer
 *   i, a positive integer
 * Purpose:
 *   Find the ith smallest element of strings.
 * Produces:
 *   ith, a string
 * Preconditions:
 *   strings contains at least size values.
 *   strings contains no duplicate values.
 *   0 <= i < size
 * Postconditions:
 *   ith is an element of strings.  That is, for some j, ith = strings[j].
 *   There are exactly i values, v, in strings that alphabetically
 *     precede ith.
 *   The values in strings may have been rearranged.
