Her new friend Rabbit is trying to hop over so they can play! More specifically, he wants to get from (0,0) to (x,0) by making multiple hops. He is only willing to hop from one point to another point on the 2D plane if the Euclidean distance between the endpoints of a hop is one of its n favorite numbers: a1,a2,…,an. What is the minimum number of hops Rabbit needs to get from (0,0) to (x,0)? Rabbit

Codeforces Round #620 (Div. 2)_D. Shortest and Longest LIS(C++_最长上升子序列)

由 旧街凉风 提交于 2020-02-17 21:06:46
Gildong recently learned how to find the longest increasing subsequence (LIS) in O(nlogn) time for a sequence of length n. He wants to test himself if he can implement it correctly, but he couldn’t find any online judges that would do it (even though there are actually many of them). So instead he’s going to make a quiz for you about making permutations of n distinct integers between 1 and n, inclusive, to test his code with your output. The quiz is as follows. Gildong provides a string of length n−1, consisting of characters ‘<’ and ‘>’ only. The i-th (1-indexed) character is the comparison

A. Three Strings 思维题 题目大意 ：给你三个长度相等的字符串s1,s2,s3，现在要求你的每一位进行如下操作： i - s1用 i - s3 替换 或 i - s2 用 i - s3 替换。问进行完操作后能否使s1=s2； 解题思想： 如果能进行操作的话，每一位必有 i - s1 = i - s3 或 i - s2 = i - s3；因为，存在i - s1 = i - s3 或 i - s2 = i - s3的话，可以将对方串与s3进行替换，这样就使得s1=s2。 AC代码： # include <bits/stdc++.h> using namespace std ; typedef long long ll ; const double PI = acos ( - 1.0 ) ; int main ( ) { ios :: sync_with_stdio ( false ) ; int t ; cin >> t ; while ( t -- ) { bool flag = 0 ; string s1 , s2 , s3 ; cin >> s1 >> s2 >> s3 ; for ( int i = 0 ; i < s1 . size ( ) ; ++ i ) { if ( s1 [ i ] == s3 [ i ] || s2 [ i ] == s3 [ i ]

让div高度撑满屏幕的方法

由 时光怂恿深爱的人放手 提交于 2020-02-17 16:11:59
在body只有一个div的时候，可以通过这样的方式让div撑满整个屏幕。 1.给div设置定位。 复习一下—— css中position有五种属性： static:默认值，没有定位 absolute:绝对定位，相对于父级元素进行定位 relative:相对定位 fixed:固定定位,相对于浏览器窗口进行定位 inherit:从父元素继承定位信息 除了默认值static和inherit之外，添加其他三种都可以实现窗口自适应。 在这里插入代码片 <style> 2 *{ 3 margin: 0; 4 padding: 0; 5 } 6 div{ 7 width:100%; 8 height: 100%; 9 background: yellow; 10 position: absolute; 11 } 12 13 </style> 14 15 16 <body> 17 18 <div></div> 19 20 </body> ---------- 2.通过将html设为高度百分百 <style> 2 *{ 3 margin: 0; 4 padding: 0; 5 } 6 html,body{ 7 width: 100%; 8 height: 100%; 9 } 10 div{ 11 width:100%; 12 height: 100%; 13 background: yellow;

Codeforces Round #620 (Div. 2) A. Two Rabbits

Being tired of participating in too many Codeforces rounds, Gildong decided to take some rest in a park. He sat down on a bench, and soon he found two rabbits hopping around. One of the rabbits was taller than the other. He noticed that the two rabbits were hopping towards each other. The positions of the two rabbits can be represented as integer coordinates on a horizontal line. The taller rabbit is currently on position x x , and the shorter rabbit is currently on position y y ( x < y x<y ). Every second, each rabbit hops to another position. The taller rabbit hops to the positive direction
