题意:1-n的全排列,求字典序第k小的。思路:这个题还是比较有意思的,也不难,右边x个数的全排列就是x!个,由k的范围,只需要考虑右边8个大数的全排列情况,剩下的小数,先输出就可以,8个数,就可以非常暴力的搞了然后依次用k/,k%就能知道当前位置应该选择第几小数,然后记得更新,就完了,,最后小心PE。。。代码:#include#include#include#include#include#inc

题目大意:迷宫问题,已知出发点和终点,求两点之间时间最短的路径,要注意,迷宫中有怪物,走到有怪物的格子要击败怪物,用时等于怪物的血量。题目解析:迷宫问题,马上想到用dfs或bfs,像这种求一条最短路线的就用bfs,由于涉及到不同血量的怪物,我们采用优先队列可以解决这个问题。题目要求输出走过的节点,我们可以定义结构体node,每次记下前驱结点,到终点用一个dfs函数输出沿线坐标;也可以从终点出发,用

这题,找了好久,都没有找到是什么规律,百度了之后,才知道是第几个最小的排列是枚举排列的第几个。真是长知识了!!~知道了这样的规律之后,就可以很快的写出了,algorithm这个头文件中又一个枚举排列的函数next_permutation,第i个最小的排列,就是调用next_permutationi-1次之后的那个排列。next_permutation同样的适用与可重集,也就是集合中存在重复元素。下

直接选择序列的方法解本题,但是最坏时间效率是O(n*n),故此不能达到0MS。使用删除优化,那么就可以达到0MS了。删除优化就是当需要删除数组中的元素为第一个元素的时候,那么就直接移动数组的头指针就可以了,那么时间效率就是O(1)了,而普通的删除那么时间效率是O(n),故此大大优化了程序。如何直接选择第k个序列,可以参考本博客的Leetcode题解。Leetcode题有个一模一样的题目。不过没有使
