sorted. This machine runs for 9 seconds and 49 milliseconds.Note: There is no bit type of programming language to implement bit manipulationTake the int type under 32-bit operating system as an example. If you need to apply n bits, you need to have a[n/32+1] int type to allow the next n bit (of course, some bits in the last int are wasted)When the position I is 1, you can use the following actions:The first bit must be in the number of int array A (I

static dump mode, you can also create a log file. Registering log files To ensure that the database is recoverable, you must follow two principles when registering a log file: 1) The Order of registration is strictly based on the time sequence of concurrent transaction execution; 2) The log file must be written before the database is written. Recovery strategy Recovery of transactional failures A transaction failure is the termination of a thing before it runs to the normal termination point
