UVa - 1153 - Keep the Customer Satisfied
用pair作为基本结构保存q和d,在用一个数组vector<pair >来存储输入数据。然后按照等待时间 d 排序,注意用sort排序默认是用first,这里的的first是q,所以要重写一个比较函数,用second排序。 接下来就是贪心算法,用优先队列priority_queue<pair > 存储结果,这里体现了用pair的优点,刚好优先队列中就是first高优先级高。 一个个入队,如果总时间超过了当前限制时间,则把队中花费时间最长的元素(就是q最大的)删掉。...

Uva - 1614 - Hell on the Markets
先考虑一个问题,总和为零,那么意味着正数之和与负数之和的绝对值相等,那么所有数的绝对值之和必定是偶数,所以先判断绝对值之和是不是偶数,不是偶数直接无解。 如果是偶数,把绝对值之和除以2就是正数之和,把输入的序列排序,然后从大到小贪心求解。因为排序之后顺序有了变化,所以用了pair存储,first是值,而second是原始序列中的位置,这样排序的时候存储位置的值也是跟着变化,但每个值的原始位置信息还保存完好。...
