题目 询问第K大的数 //这是我最初的想法,用multiset,AC了——好吧,也许是数据弱也有可能 //multiset运用——不去重,边插入边排序 //iterator的运用,插入的时候,如果是相同的数没直接放在相同的现有的数据后面的 #include<cstdio> #include<cstring> #include<algorithm> #include<set> using namespace std; //#define IN freopen(…

题意:输入n行,k,如果一行以I开头,那么插入x,如果以Q开头,则输出第k大的数 用优先队列来做,将队列的大小维护在k这么大,然后每次取队首元素就可以了 另外这个维护队列只有k个元素的时候需要注意一下,先将输入的数都插入之后再将多余的数弹出去,这样才能保证留在队列里面的数是前k大的数 另外想到set里面的数是从小到大排列好了的,每次取第k个元素,但是超时了= = #include<iostream> #include<cstdio> #include<cstring>…
