这道题的意思是
finds the minimal number of elements in a set containing at least two different integers from each interval.
0 1 2 3 4 5 6 7
-----           (0 to 2)
    -----       (2 to 4) 
      -------   (3 to 6)
        ------- (4 to 7)
包含上面集合的至少两个元素的集合???
这里需要的最小的集合是(1,2,4,5) or (1,2,4,6) 注意这里的集合不需要是连续的数字,题目只要求出这种集合的元素个数,
所以输出:4

the minimal number of elements in a set原来是集合中元素的最少个数的意思 ==。而且说的是每一个区间 (34) liuyu523115237 2011-08-09 16:05:05
