Rsplit (Sep[,maxsplit]): Same as split (), but starting from the right.　　Look at the following examplestr1 = ' ab c\n\nde

with crontab, edit or delete the corresponding job. The Guardian means not to be controlled by the terminal. Most of Linux's servers are implemented with daemon processes. For example, Internet server Inetd,web server httpd and so on. At the same time, the daemon completes many system tasks. For example, the job planning process Crond, the print process LPD, and so on. The foreground process is the process that the user uses to have the control terminal shell, process foreground and background

fiber for optical devices With the construction and expansion of a large number of optical communication networks, the consumption of active and passive devices is increasing. The most widely used fiber-optic devices, mainly optical fiber amplifier, fiber coupler, optical divide wave, fiber Bragg grating (FG), AWG and so on. These optical devices must be low loss, high reliability, easy to use and communication optical fiber for low loss coupling an

The algorithm must use two one-dimensional arrays, setptab[] and index_adjust[], appended to the following code. -------------------------------------------------------------------------------- IMA-ADPCM Compression Process First of all we think that the sound signal is zero-based, so we need to initialize two variables int index = 0,prev_sample = 0; In actual use, however, the value of Prev_sample is the first sampled value in each block. (This is explained in detail in

:? -Findgoal (AV (problem, x), CF ). the predicate must handle three cases: ● known "Attribute-value"; ● A predicate can infer "Attribute-value"; ● the predicate must ask the user. You can define a new predicate: askable (live, 'where does it live? '). The question to ask is live. The question is: 'where does it live? Then, you can write the predicate findgoal. Known attribute values: findgoal (AV (ATTR, Val), CF):-fact (AV (ATTR, Val), CF ),!. Ask the user about the attribute values: findgoal

Some file groups that store partitions are too large. You 'd better split them. 1. First, find the partition number corresponding to the file group to determine the new boundary value to be set based on the Partition Number. 2. Add new file groups and files 3. Set the new file group to next used. 4. Modify the Partition Function and split the partition. Detailed steps: 1. Locate the Partition Number Use [dB] Go -- select FG for the file group to be
