recycle them periodically by releasing the unreachable nodes and returning them to the free list. Whenever a heap space is required, the application invokes the malloc function in the usual way, and if malloc cannot find a suitable free block, it calls the garbage collector, hoping to reclaim some garbage to the idle list Second, after-school exercises 1.

. Exercises 9.3 Given a 32-bit virtual address space and a 24-bit physical address, for the following page size p, determine the number of bits of Vpn,vpo,ppn,ppo "Supplement: vpn--virtual page number; vpo--virtual page offset; ppn--physical page number; ppo--physical page offset""Understanding: We have 32 virtual address bits and 24 physical address bits, and the page size is 1KB, which means that for VPO and PPO, 10 bits are required (to differentiate the 2^10 specific units with

How would you print just the 10th line of a file?For example, assume file.txt . Has the following content:Line 1Line 2Line 3Line 4Line 5Line 6Line 7Line 8Line 9Line 10Your script should output the tenth line, which is:Line 10[Show hint]Hint:1. If The file contains less than ten lines, what should do you output?2. There ' s at least three different solutions. Try to explore all possibilities.This topic can only use bash, previously did not pay much attention to Leetcode show hint, today acciden

, you can use the tail command, such: tail-10/etc/passwd or tail-n 10/etc/passwd tail-f/var/log/messages parameter-f keeps tail reading the latest content, in this way, you can use Ctrl + c to terminate real-time monitoring! 3. view the middle part of the file, you can use the sed command, such as: sed-n'5, 10p'/etc/passwd so that you can only view the join command of lines 5th to lines 10th of the file. the join command can merge and output the conte

Linux tail command analysis 1. to view the first five lines of a file, you can use the head command, such as head-5/etc/passwd2. to view the last 10 lines of the file, you can use the tail command, such: tail-2/etc/passwd or tail-n2/etc/passwdtail-f/var/log... linux tail command analysis 1. to view the first five lines of a file, run the head command, for example, head-5/etc/passwd 2. run the tail command to view the last 10 lines of the file, for example: tail-2/etc/passwd or tail-n 2/etc/passw

can use the sed command, for example, sed-n'5, 10p'/etc/passwd, to view only rows 5th to 10th of the file. 　　 4. calculate the number of files and directories. the following statement can help you calculate the number of files and directories .. # Ls-l * | grep "^-" | wc-l ---- to count files # Ls-l * | grep "^ d" | wc-l ----- to count dir You can also convert the preceding statement into a script or an alias statement. 　　 5. the method to only list

. after Win9x is reinstalled, lilo cannot start Linux. You only need to start Linux with a floppy disk and run lilo once. For RedHat, run mkbootdisk to create a boot disk. for example: Mkbootdisk -- devices/dev/fd0 2.0.34-1. 2.0.34-1 is a directory under/lib/modules. 11. remove the lilo information in the pilot zone. After lilo is installed, if the number or partition of the hard disk changes, the hard disk cannot be started. in this case, you only need to use a floppy disk to start dos and then

indicating that the product from xI to XJ, inclusive Must be calculated ( 1IJN). Within each test case there was at least one product command. output For Each test case output a line with a string representing the result of the the product commands in th E test Case. The i -th character of the string represents the result of the i -t H product command. If The result of the command is positive the character must be ' + ' (plus);

Example The code is as follows Copy Code #include #define SIZE 4int main (void){Short dates[size];Short * PTI;Short index;Double bills[size];Double * PTF;PTI = dates;PTF = bills;printf ("%23s%10sn", "short", "double");for (index = 0; index printf ("Pointers +%d:%10p%10pn", index, PTI + index, PTF + index);return 0;} First of all: In C, the result of adding 1 to a pointer is to add a storage unit to the pointer,

, each representing an operation. There is kinds of operations, as described below:1) P a b CA, B and C are integers. This operation means the mayor X painted all segments from segment A to segment B with color C (0 2) Q a BA and B are integers. This is a query operation. It means that someone asked what many kinds of colors were there from segment A to segment B (0 Please note that the operations is given in time sequence.The input ends with M = 0 and N = 0.Outputfor each query operation, print
