examine per transmitter. No points is at the same location as the transmitter.InputInput consists of information for one or more independent transmitter problems. Each problem begins with one line containing the (x, y) coordinates of the transmitter followed by the broadcast radius, R. The next line contains the number of points N in the grid, followed by N sets of (x, y) coordinates, one set per line. The end of the input is signalled by a line with a negative radius; The (x, Y) values are pre

confused with precision. High Accuracy means that the repetition error and system error are relatively small, and the measurement data is concentrated near the true value. Figure 1 illustrates the meaning of the three words mentioned above when a dart is used as an example. The target value position is represented by the target. Figures 1 (a) and (B) Indicate the good and bad shooting accuracy, that is, the system error size.

commands are almost all public in each version control tool. Next we will try some unique git commands: Git branch: add, delete, and query branches, for example, 'git BranchNew_branch creates a new branch named new_branch from the current working version, 'git branch-dNew_branch will forcibly Delete the branch called new_branch, and 'git branch' will list all local branches Git checkout: git checkout has two functions: one is to switch between different branchs, for example, 'git checkoutNew_br

The concept is an absolute form. In addition to the perf

, this is ignored. The probability of taotao burst is 7.4%. If taotao burst, it is equivalent to one more card. Therefore, the mathematical expectation of taotao burst is 2*0.926 + 3*0.074 = 2.074, with a total of 3 points of blood, therefore, the total number is 6.22. Because the yellow cover card is basically fixed, and there are only 12 cards in total, there is basically no more, and the 12 cards can do more limited, and in case they are not made, the next round will basically disappear.

phones, general gyroscope manufacturers are rarely eye-catching. Of course, driven by the iPhone 4, the foreseeable mobile phone arms competition will sooner or later make the gyroscope more popular. The main function of gyroscope is to measure the rotation rate along a specific coordinate axis based on the theory of conservation of angular momentum. During use, the rotor of the gyroscope always points to a fixed direction during high-speed rotation. When the movement direction of the moving ob
