2018 Multi-University Training Contest 9 Solution

A - Rikka with Nash Equilibrium 题意:构造一个$n * m$的矩阵,使得$[1, n * m]$ 中每个数只出现一次,并且纳什均衡只出现一次. 思路:从大到小的放置,每一个都可以拓展一行拓展一列或者放在已经拓展的行列焦点,用记忆化搜索/dp即可 #include<bits/stdc++.h> using namespace std; typedef long long ll; int n, m; ll p; ll dp[][][ * ]; ll DFS(int…

Instant Complexity - POJ1472

Instant Complexity Time Limit: 1000MS Memory Limit: 10000K Description Analyzing the run-time complexity of algorithms is an important tool for designing efficient programs that solve a problem. An algorithm that runs in linear time is usually much f…

Runtime Complexity of .NET Generic Collection

Runtime Complexity of .NET Generic Collection I had to implement some data structures for my computational geometry class. Deciding whether to implement the data structures myself or using the build-in classes turned out to be a hard decision, as t…

Examples of complexity pattern

O(1):constant - the operation doesn't depend on the size of its input, e.g. adding a node to the tail of a linked list where we always maintain a pointer to the tail node.int i=0;i++;++i;i+=6; O(n):linear - the run time complexity is proportionate to…

2016暑假多校联合---Rikka with Sequence (线段树)

2016暑假多校联合---Rikka with Sequence (线段树) Problem Description As we know, Rikka is poor at math. Yuta is worrying about this situation, so he gives Rikka some math tasks to practice. There is one of them: Yuta has an array A with n numbers. Then he make…
