If you use Dijkstra directly, you can only get 22 and four cases.

I found a pitfall on the Internet, that is, the vehicles at the back of the site cannot transport the site before the meeting. Therefore, there will be four tests that fail and need to be implemented by dijskstra + DFS. Save all the paths.
Make up later.

Binary Apple TreeTime limit: 1.0 secondMemory limit: 64 MBLet's imagine how apple tree looks in binary computer world. you're right, it looks just like a binary tree, I. e. any biparous branch splits up to exactly two new branches. we will enumerate by integers the root of binary apple tree, points of branching and the ends of twigs. this way we may distinguish different branches by their ending points. we will assume

Description
It is known that an array has been arranged from small to large, indicating a platform in this array.(Plateau) is a continuous element with the same value, and this element cannot be extended.Stretch. For example, in 2.2, 4,5.5 and 6 are all platforms. Write a program to receive an array.Find the platform. In the preceding example, 3.3.3 i
Title Description:
reading the scores of n students, the number of students will be output for a given score.
Input:
The test input contains several test cases, each of which is in the format
Line 1th: N
Line 2nd: The results of n students, two adjacent numbers with a space interval.
Line 3rd: given score
The input ends when the n=0 is read. where n is not more than 1000, the score is (contains) an integer be
format:the i-th Line (1≤i≤n) starts with mi (1≤mi≤100), the number O F manufacturers for the i-th device, followed by mi pairs of positive integers on the same line, each indicating the BANDW Idth and the price of the device respectively, corresponding to a manufacturer.OutputYour program should produce a single line for each test case containing a single number which is the maximum possible b/p For the test case. Round the numbers in the output to 3 digits after decimal point.Sample Input1 33

Practice:
1: N is very small. It should be visually compressed DP
2: a single line will go through at least two points (otherwise it will be too deficient), so we can enumerate two points, preprocessing the state of the point set passing through the straight line of the two points (DP [I] [J])
3: Then you can perform the Memory search. Each time
