Problem: Takahashi made N problems for competitive programming. The problems are numbered 1 to N, and the difficulty of Problem i is represented as an integer d_i (the higher, the harder).  He is dividing the problems into two categories by choosing an integer K, as follows:    * A problem with difficulty K or higher will be _for ARCs_.   * A problem with difficulty lower than K will be _for ABCs_.  How many choices of the integer K make the number of problems for ARCs and the number of problems for ABCs the same?
