. Therefore, binary search can be used with linear search.For example, find a number that does not exist in a range. For example, if there is a set of numbers, the range of each number is [1-100], and find a number within [1-100, but does not belong to the set. Divide the set into two parts. The range of the first part is [1-50], and the second part is [51-100].If the number in a set is less than 50, it indicates that the number in the range is smaller, and the search continues in the range.

Compared with the 256 byte/Page algorithm, there are not many changes, but to be honest, there are only a few changes, which took me a whole day, I don't fully understand whether the original Chu algorithm dared to work ~ Sramecc. h stores the ecc_precalc_table. This table contains 65536 pre-calculated verification codes, of which the low 8 bits are the column check bits and the 8th bits are the row che
, if origin is used, there will be no such problems. The type is undoubtedly point3d class, and even if it inherits from virtual base class, the offset position of members will be fixed during the compilation period.

1. Introduction:
The STM32 can support 68 external interrupt channels, which have been fixed to the corresponding external devices. Each interrupt channel has its own interrupt priority control byte Pri_n (8-bit, but only 4-bit in the STM32, high 4-bit valid) there can be 5 groups in total:
Group No. 0: All 4 bits are used to respond to interrupts
bit7 bit6 bit5 bit4 bit3 bit2 bit1 bit0
Group 1th: Maximum 1 bits for preemption priority, lower 3 bits
A simple example is provided to solve this problem.[Cpp]Class Concrete{Public:Private:Int val;Char c1;Char c2;Char c3;};Class Concrete1{Public:Int val;Char bit1;};Class Concrete2: public Concrete1{Public:Char bit2;};Class Concrete3: public Concrete2{Public:Char bit3;};Int main (){Concrete2 * pc2;Pc2-> val = 10;Pc2-> bit1 = 'a ';Pc2-> bit2 = 'B ';Concrete1 * pc1_1, * pc1_2;Pc1_1 = pc2;* Pc1_2 = * pc1_1;Cout

In principle, the board was infinite, which would cause problems when the active area encroaches the border of the array. How would address these problems?Credits:Special thanks to @jianchao.

Tbitmap internally manages an array of objects, and the access index is also a pointer.

register, but is interpreted as sending a command to i8042. If the command receives a parameter, the parameter is sent to the $ port. Similarly, any return structure of the command can be read out from the port. The status flag for i8042 is read from the $64 port. They contain error messages, status information, and an indication that there is no data in the input and output buffers. These flags are defined as follows:Bit7 Bit6 Bit5 Bit4 Bit3 Bit2 Bi
