bit by bits

Introduction Most of the optimizations that go into topcoder contests are high-level; that is, they affect the algorithm rather than the implementation. however, one of the most useful and valid tive low-level optimizations is bit manipulation, or

Review bits operation (bit operation), 32bit integer value range: -2^31--2^31-1 0 1 1 1 1 1 1 1 = 127 0 0 0 0 0 0 1 0 = 2

For ix86 programming, sometimes it is necessary to change from the real mode to the protection mode (for example, to access extended memory in the DOS era, or to write pilot code, of course, if you program in a 32-bit operating system, you won't be

Counting bits set (naive)unsigned int v; Count the number of bits set in Vunsigned int c; C accumulates the total bits set in Vfor (c = 0; v; v >>= 1){c + = v & 1;}The naive approach requires one iteration per bit, until no more bits is set. So in a

A bit segment is a special struct that is used less in the C language, and the C language allows you to specify the memory length of its members in bits in a struct, which is called a bit field or bit field in bits. Use bit segments to store data
