DescribeIn the 2008 Beijing Olympics, a country's athletes participated in the N-Day final project (1≤N≤17). Now we need to count the number of gold, silver, bronze medals and total medals received by country A.Enter input n+1 line, line 1th is the number of days that a country participates in the final project N, followed by n lines, each row is the number of gold, silver, bronze medals obtained on one day of the country, separated by a space. Output 1 lines, including 4 integers, the total num

you make a minor change, and roll back if you have a problem Experience You can see that the whole process needs to run tests over and over again, and if a test runs for a long time, it inevitably leads to very low development, so you can write different levels of testing, write for different big functions and small functions, rather than running the biggest test that involves the most each time. Writing tests is bound to take a little time, but once wri

Lattice is the inventor of ISP technology and has certain characteristics in the application of small-scale pld. Early Xilinx products generally do not involve military and aerospace-grade markets, but there are many products such as Q Pro-r that

according to its specifications using the servo track Writer, Through its head in media for a lap of Embedded Servo.100gb=107,374,182,400 byte/512byte=209,715,200 Sector.Because too fine, Servo write is laser control, no misunderstanding. Because media is circular, the diameter is smaller, so the number of sector is less than the diameter, this is called the Zone Bit recording code, this is the most difficult technology.Embedded Servo completed, this time the hard disk is ready to use, connecte

double. On machines that support IEEE floating-point format, these data types correspond to single-precision and double-precision floating-point.The newer version of the C language, including the ISO C99, contains the third floating-point data type long double. For many machines and compilers, this data type is equivalent to a double data type. However, for Intel compatible machines, GCC uses the 80-bit "extended precision" format to implement this data type, providing a much larger range and p

Description: After the use of IP to identify each network node, if the two nodes separated by multiple network nodes to communicate, need to "man-in-the-middle" strings, the step by step notice a node data, to go to the end of the node step-by-step how to go.Static routing: Manually configure static routing information that can be forwarded using a leased line interface or a next-hop IP address based on the routing information when forwarding packets with matching destination addresses.Advantage

Although each routing protocol has its own metrics, the metric values between the different protocols have different meanings and are not comparable. The router must choose the best path computed by one of the routing protocols to join the routing table as a forwarding path.In the actual application, the router chooses the routing protocol based on the route priority.

PHP/*1.PHP Create file-the fopen () fopen () function is also used to create Files. Maybe a little confusing, but in PHP, the function used to create the file is the same as the open file if you open a file that does not exist with fopen (), This function creates the file, assuming that the file is opened to write (w) or increase (a). The following example creates a new file named "testfile.txt". This file will be created in the same directory where the PHP code is located: $myfile = f
