Input t – the number of numbers in list, then t lines follow [t <= 10^6].  Each line contains one integer: N [0 <= N <= 10^6] Output Output given numbers in non decreasing order. Example Input: 5 5 3 6 7 1 Output: 1 3 5 6 7 大数据的排序,输入和输出. 一開始使用了co…

题目链接:Turbo Sort 用java自带O(NlogN)的排序就可以,java要特别注意输入输出.输入用BufferedReader,输出用printWriter.printWriter的速度比System.out快很多,参考StackOverflow. 代码: import java.io.BufferedOutputStream; import java.io.BufferedReader; import java.io.InputStreamReader; import java.i…

Sorting is not an out-dated topic. My own in-place qsort got TLE... so, I simply called stl::sort() to get AC. This thread explains everything: http://stackoverflow.com/questions/5038895/does-stdsort-implement-quicksort Basic qsort has a worst case o…

def heap_sort(ary): n = len(ary) first = int(n / 2 - 1) for start in range(first, -1, -1): # 3~0 revese max_heapify(ary, start, n - 1) # from start for end in range(n - 1, 0, -1): ary[end], ary[0] = ary[0], ary[end] max_heapify(ary, 0, end - 1) retur…

找一个数组中两数之间最小的不同值. 思路: 1 排序 2 后前相减,比較得到最小不同值 三个数甚至很多其它数之间的不同值都是这么求了,时间效率都是O(nlgn) -- 排序使用的时间 原题: http://www.codechef.com/problems/HORSES 笔者的练习文件非常大,所以还是使用类好,能够降低变量名和函数名的冲突. namespace有时候也不好用. #include <cstdio> #include <algorithm> #include <a…

Content 请编写一个"频率排序器".输入一个 长度为 \(n\) 的数列 \(A=\{a_1,a_2,\dots,a_n\}\),要求: 按照每个数的出现次数降序排列. 如果两个数出现次数相同,则谁在数列中出现的位置靠前,排列之后那个书的位置也是靠前的. 数据范围:\(n\in[1,10^3],1\leqslant a_i\leqslant c\leqslant10^9\). Solution 我们开个 \(\texttt{map}\) 数组 \(vis\) 用来记录某个数是在数…

There are K nuclear reactor chambers labelled from 0 to K-1. Particles are bombarded onto chamber 0. The particles keep collecting in the chamber 0. However if at any time, there are more than N particles in a chamber, a reaction will cause 1 particl…

选择出数列中前k个最大的数. 这里由于数据特殊.所以能够使用hash表的方法: #include <cstdio> #include <algorithm> #include <stdlib.h> #include <limits> using namespace std; const int SIZE = 1000005; const int SMALL = -500000; bool arr[SIZE]; int main() { int n, m, a…

Problem Description 给你n个整数,请按从大到小的顺序输出其中前m大的数. Input 每组测试数据有两行,第一行有两个数n,m(0<n,m<1000000),第二行包含n个各不相同,且都处于区间[-500000,500000]的整数. Output 对每组测试数据按从大到小的顺序输出前m大的数. Sample Input 5 3 3 -35 92 213 -644 Sample Output 213 92 3 Hint请用VC/VC++提交 Author LL Source…
