first call to system call Sys_getenvid isAnd then after entering the Umain functionIt outputs two times, so it generates two system callsWhen the Umain function executes and returns to the LibMain function, the Exit function is executed, and the exit function is called inside Env_destroySo the above interrupts and system calls are explained.Page Fault and memory protectionVery important content, protect memory, in the memory operation, check the current memory range is not the current process c

addressing hash table, α=n/mThus, if α=50% so expected to explore the number of 2, if α=90%, the expected number of exploration will be significantly increased to 10, so in this strategy, the size of α is very important (Lenovo to the same day birthday problem, also this reason), in engineering some of the hash table using this strategy will force α less than 75%, If this value is exceeded, the hash table is automatically expanded.The expected number of search 1/(1-α) is how to calculate, as fo

　　Baidu Encyclopedia:Quicksort is an improvement of Bubble sorting, which was proposed by C. A. R. Hoare in 1962. Its basic idea is: Split the data to be sorted into two independent parts by one sort, and all the data in one part is smaller than all
