Recently, because of the relationship between Sino-2 and Beidou, many netizens posted the Tle data indicating the orbit of the satellite. Here is a brief introduction to the satellite orbital parameters and the format of the tle. Although no one actually reads the TLE data directly, it is the use of software to obtain satellite orbit and location information, but

Test instructions: There are M machines, there are n tasks. Each task must be done in SI or later, completed before EI or, the completion task must process the PI time unit. where each task can work on any (idle) machine, each machine can only work one task at a time, and each task can only be worked by one machine at a time, and the task is half-interrupted and taken to other machines. Can you finish the task within the stipulated time?The map is simply classic. Just beginning to see is also a

Oh, another 1wrong, really test my patience, and even more I put the end of the wrong condition, variable name mixed, define the global and define local variables.This time again the problem of initialization, say, why the diagram initialized to-inf to timeout, initialized to 0 a.Test instructions:

Test instructions: Soda has a $n$ point $m$ side of the dichotomy, he wants to add edge to make this graph into a number of sides of the most complete binary graph. So he wanted to know how many new edges he could add. Note that heavy edges are not allowed.Idea: Two-figure coloring this simple, mainly DP, there is a time limit. I think it should be to find out all the connected components, the number of points on each side of the connected component is stored, followed by a unified DP. But!! Tim

B. Pasha and StringThe topic is simple, that is, the string from one position to another position between the fragments in reverse order, the basic idea is to use swap 22 exchange. At this point the problem is the time limit exceeded, 22 exchange too time-consuming, because there is exchange in the past and exchange back to the equivalent of no change in exchange wasted time, there is no better way? Because the upside is the middle number, so you can count the number of times each letter in the

determine the shape of the track, whether it is an ellipse or a circle, and how large the ellipse is. The two quantities of 3 and 4 determine the position of the satellite orbital plane in space, but in which position the orbit in the orbital plane is uncertain. 5 This value combines the orbital shape and the orbital plane to determine the position of the track in the orbital plane. 6 determines the position of the satellite at some point in time, so that a complete orbit is determined.2.

1, the Tle Rail report:Next, the significance of the contents of the Tle Rail report is as follows:2. SGP4 Model:The SGP4/SDP4 model developed by NORAD is needed for the calculation of satellite orbits in the tle orbit, and the SGP4 model was developed by Ken Cranford in 1970 for the Near Earth satellite, which is a broad solution to Lane and Cranford (1969).

Recently has been practicing with the Java writing problem (link), today did not want to find a very simple two-part problem, I started is directly open int[] array call Arrays.sort () to sort, did not think of Tle, originally because the JDK for int[] sort is the use of fast sorting, The relevant call source code in JDK is as follows1 Public Static void sort (int[] a) {2 null, 0, 0); 3 }View CodeAnd the test data just has the anti-fa

This question requires the largest sum of consecutive subsequences. So when I see the question, I think of listing all the situations and comparing the two, taking the maximum value (that is, the meaning of updating the maximum value), this idea is very simple, but it will time out, the time complexity is O (n ^ 3), because there are three for statements

The second line is an integer m (0 ,represents the number of the defensive towers owned by Xiao Xin. next M line ,Each line consists of three integers Li, ri, di (1 ,represents the attack range of the Tower of defense.[L, R] and the damage value of the tower. Next an integer K (0 , representing the number of monsters.

Given a square, each point in the grid is composed of an open space, lawn, and a wall. A robot can be placed in each blank space, and each robot can scan the laser in four directions, therefore, a solution should be given to place enough robots on the board. The laser can pass through the lawn but cannot pass through the wall.
Solution: in fact, this is a classic binary match diagram. The practice is to split rows and columns, that is, if a row contains a wall, when the front and back of the wal
