思路 经典的k路归并问题 问题先转换为2路的有序表归并 先让A[1~k]都和B[1]相加,然后加入堆中,取出堆顶(A[x]+B[y])之后,再放入A[x]+B[y+1] 代码 #include <cstdio> #include <cstring> #include <algorithm> #include <queue> using namespace std; struct QNode{ int val,s; bool operator < (co…

题面 背景 输入 输出 翻译(渣自翻) 给定K个包含K个数字的表,要求将其能产生的\( k^{k} \)个值中最小的K个输出出来 题解 k路归并问题的经典问题 可以转化为二路归并问题求解 考虑A[],B[]两个有序数组 使用堆,记录一些二元组\( (x,y) \),x表示值,y表示对应的b的下标,因为我们是把b合并到a上,所以我们能够根据记录的下标推出后面的值 然后两两合并 所以就很简单 放代码 #include <cstdio> #include <algorithm> #inc…
