The term "most suitable" is defined as follows. An integer m greater than 4 is given. A positive fraction a / b less than or equal to 1 is also given. The area of the picture should not be greater than m. Both of the width and the height of the translated picture should be ...
The input is terminated by the end of file. Output For each test case, you should output how many ways that all the trains can get out of the railway. Sample Input 代码语言:javascript 代码运行次数:0 运行 1 2 3 10 Sample Output 代码语言:javascript 代码运行次数:0 运行 1 2 5 16796...
and you have to fight 1vN. There are two key attributes for the heroes in the game, health point (HP) and damage per shot (DPS). Your hero has almost infinite HP, but only 1 DPS. To simplify the problem, we assume the game ...
The skater has to jumpfrom the outside edge of one skate, turning in the air. “Double" or "triple" refers to the number ofrotations (旋转) the skater completes before landing. The term is a ittle misleading given that the skaterhas to do an extra half rotation, meaning that for a ...
How many ways can the numbers 1 to 15 be added together to make 15? The technical term for what you are asking is the "number of partition" which is often called P(n). A partition of n is a collection of positive integers (not necessarily distinct) whose sum equals n.Now, I will...
In information theory and computer science, the Levenshtein distance is a string metric for measuring the amount of difference between two sequences. The term edit distance is often used to refer specifically to Levenshtein distance. The Levenshtein distance between two strings is defined as the mini...
By saying “digest sum” we study some properties of data. For the sake of simplicity, our data is a set of integers. Your code should give response to following operations: 1. add x – add the element x to the set; 2. del x – remove the element x from the set; ...
HintFor the first Sample Input, we let train 1 get in, then train 2 and train 3. So now train 3 is at the top of the railway, so train 3 can leave first, then train 2 and train 1. In the second Sample input, we should let train 3 leave first, so we have to let train 1...
We are planning a similar project. Your task in the project is to find the most suitable width and height of the translated rectangular picture. The term "most suitable" is defined as follows. An integer m greater than 4 is given. A positive fraction a / b less than or equal to 1 is...
The cavern’s structure is like a tree in such a way that there is one unique path leading to each room from the entrance. To finish the battle as soon as possible, you do not want to wait for the troopers to clear a room before advancing to the next one, instead you have to ...
