leetcode 88. Merge Sorted Array 合并到一个新的数组,直接比较就好了,这个题目是将nums1、nums2合并到nums1,nums1有许多多余的空间 如果按照合并到一个新的数组从小比到大的方式进行比较,就需要每次挪动nums1的数组。 本题可以采用从大到小的比较方式,这样就不用每次挪动数组。 同时注意,m和n都是可以为0的,...

7. Merge Two Sorted Arrays (Descending)Write a program in C to merge two arrays of the same size sorted in descending order.This task requires writing a C program to merge two arrays of the same size and sort the resulting array in descending order. The program will take inputs for ...
merge()是C++标准库的函数,主要实现函数的排序和合并,不仅仅是合并,具体要求参照标准库。include"stdafx.h"include<iostream> include<algorithm> include<array> include<list> usingnamespacestd;boolcomp(constinti,constintj){ returni>j;} intmain(void){ /*自定义谓词*/ std::array<int,4>...
//本程序实现了既可以保留merging过程中的temp⽂件,也提供的删除temp⽂件,只保留sorted 和unsorted 的⽂件的⽅式,具体调整在函数clear_external_memory()中,//可以注释掉,也可以让其运⾏ /*Group 1. An attempt to sort a large file of integers, breaking the large file into arrays of 1000 ...
时间复杂度 还是这张图,可以看出,一共有logn层,每一层合并的复杂度为O(n) ,也就是 T(n) = 2T(n/2) + O(n) = 2(2T(n/4) + O(n/2)) + O(n) = ... 假设n = 1时,T(1) = c,则T(n) = 2T(n/2) + cn = 2(2T(n/4) + cn/2)) + cn = ... =cnlog...
The source code was compiled using g++ -O3 -w -fpermissive bench.c. It measures the performance on random data with array sizes ranging from 10 to 10,000,000. It's generated by running the benchmark using 10000000 0 0 as the argument. The benchmark is weighted, meaning the number of ...
