判断插入排序很好判断,不是的话那就是归并排序了. 由于归并排序区间是2.4.8开始递增的,所以要判断给出的归并排序执行到哪一步,就要k从2开始枚举. 然后再对每个子区间进行一下sort即可. #include <iostream> #include <cstdio> #include <algorithm> #include <string.h> #include <cmath> using namespace std; ; int num1[m…

一.技术总结 看到是一个two pointers问题,核心是要理解插入排序和归并排序的实现原理,然后判断最后实现 可以知道a数组和b数组怎么样判断是插入排序还是归并排序,因为插入排序是来一个排一个,所以知道当发现有位置当前数比后面大时,进而再判断后面的每一位是否啊a.b数组都相等,如果是那么就是插入排序,再在后面进行一轮排序即可.如果不是就是归并排序.最主要的问题是判断归并排序到哪一轮了,使用while循环模拟归并排序,对数组a进行归并排序,直到与数组b相等,再进行一轮排序就是输出结果了. 二.…

PAT甲级1089. Insert or Merge 题意: 根据维基百科: 插入排序迭代,消耗一个输入元素每次重复,并增加排序的输出列表.每次迭代,插入排序从输入数据中删除一个元素,在排序列表中找到它所属的位置,并将其插入到该列表中.它重复,直到没有输入元素保留. 合并排序工作如下:将未排序的列表分为N个子列表,每个子列表包含1个元素(1个元素的列表被视为排序).然后重复合并两个相邻的子列表以生成新的排序子列表,直到只剩下1个子列表. 现在给出整数的初始序列, 连同一些序列,这是一些排序方法的…
