题目链接 https://www.patest.cn/contests/pat-b-practise/1085 思路 结构体排序 要注意几个点 它的加权总分 是 取其整数部分 也就是 要 向下取整 然后这个操作要在排序操作之前 不能在输出的时候 进行 不然最后一个测试点 过不了 因为 假如 有两个学校的分数 分别是 195.1 195.2 如果排序按照这个排 就是 195.1 < 195.2 就会按照 总分来排 但实际上 向下取整之后 都是195 所以应该按照 考生人数 或者是单位码来排的 还有…

题意: 给定一次PAT测试的成绩,要求输出考生的编号,总排名,考场编号以及考场排名. 分析: 题意很简单嘛,一开始上来就,一组组输入,一组组排序并记录组内排名,然后再来个总排序并算总排名,结果发现最后一个测试点超时. 发现自己一开始太傻太盲目,其实只要一次性全部输进来,记录好考场编号,一次排序就可以了.既然只排了一次,怎么计算考场排名呢,这里我用了三个数组 ];//记录各个考场当前排到的名次 (当前最后一个人的名次) ];//记录个考场当前排到的最后一个人的分数 ];//记录个考场当前已经排好队…
