; then, because we are not developing local programs, we need to use a server to start the program containing debugging information on the target machine (arm). Of course, there must be a certain data sharing mode (such as nfs) between the local machine and the target machine and a certain communication mode (such as Ethernet or serial port). Finally, start a GDB client on the local machine, you can log on to the server of the target machine to debug the program. There are also many articles on

Contariner element (. col-xx-xx is 30px relative to. Container), so the first grid element element and the last grid element need to be set to {padding-left:0px;}, { padding-right:0px}. This solves the problem of alignment, but after setting, the width of the displayed content has a 15px difference, although the width of each grid is

,-) 2 BINOMIAL-HEAP-EXTRACT-MIN(H) 4. Application Status Under what circumstances should we use "two items Heap "? If Union operations are not supported, the data structure of a normal heap is an ideal data structure. However, if you want to support merge operations on a set, it is best to use two heaps or a Fibonacci heap. The worst case for a normal heap in a union operation is O (n ), but the two heap and the Fibonacci heap are O (lgn ). Binary heap binomial heap () Fibonacci heap Binary h

If an optical drive does not read the disk, we first add electricity and put a genuine disc to see if the panel lights flashing, there is no "Tatsu, Da, da" sound, if there is, then we can conclude that the laser head and the main bearing of the sensor is broken.

that two bytes are used, and the maximum bit of each byte is 1. In the computer, the first part of the complement code is the sign bit. 1 indicates a negative number, Therefore, each byte of the internal code of the Chinese character machine represents a negative decimal number. Therefore, the statistical input string contains several Chinese characters, You only need to find the number of characters in the string smaller than 0, and divide it by 2 to get the answer */ # Include # Include Char

First, use scientific notation to represent n ^ n = A * 10 ^ X; for example, n = 3; 3 ^ 3 = 2.7*10 ^ 1; The rightmost number we require is (INT) A, that is, the integer part of; OK, and then obtain the base-10 logarithm lg (N ^ n) = lg (A * 10 ^ X) on both sides ); Simplify N * lg (n) =
