• Problem: https://judge.u-aizu.ac.jp/onlinejudge/description.jsp?id=ALDS1_4_B

Depends on

• 二分探索 配列中 以上の要素数 (library/search/binary_search/bi_ge_cnt.hpp)
• 二分探索 配列中 より上の要素数 (library/search/binary_search/bi_gt_cnt.hpp)
• 二分探索 配列中 以下の要素数 (library/search/binary_search/bi_le_cnt.hpp)
• 二分探索 配列中 未満の要素数 (library/search/binary_search/bi_lt_cnt.hpp)
• テンプレート (template/template.hpp)
