编程之美 2013 全国挑战赛 资格赛 题目二 长方形 - CYJB - 博客园

在 N × M 的网格上，放 K 枚石子，每个石子都只能放在网格的交叉点上。问在最优的摆放方式下，最多能找到多少四边平行于坐标轴的长方形，它的四个角上都恰好放着一枚石子。

输入

输入文件包含多组测试数据。

第一行，给出一个整数T，为数据组数。接下来依次给出每组测试数据。

每组数据为三个用空格隔开的整数 N，M，K。

输出

对于每组测试数据，输出一行"Case #X: Y"，其中X表示测试数据编号，Y表示最多能找到的符合条件的长方形数量。所有数据按读入顺序从1开始编号。

数据范围

1 ≤ T ≤ 100

0 ≤ K ≤ N * M

小数据：0 < N, M ≤ 30

大数据：0 < N, M ≤ 30000
