Viewing a file is a few of the ways that you create the week summarizes the following three methods:
1. Using the LS command to combine the grep method:
Ls-l--time-style ' +%a ' | Grep-e "tuesday| Wednesday "
2. Method of using awk 1:
[Oracle@bys3 ~]$ ls-l--time-style ' +%a ' |awk ' $6== ' Friday ' | | $6== "Tuesda
The following three methods are summarized to view how files are created on a day of the week:1. Use the ls command in combination with grep:Ls-l -- time-style '+ % a' | grep-E "Tuesday | Wednesday"2. Use AWK Method 1:[Oracle @ bys3 ~] $ Ls-l -- time-style '+ % a' | awk' $6 = "Friday" | $6 = "Tuesday" {print $0 }'-Rw-r
Why do you write this project?The company ui3.0 to use the Android L dialog style, but the original code dialog call way of confusion (not I write, not I wrote >_ Solution SolutionsThinking twice, I decided to use the adapter design pattern to accomplish this task. That is to say that all the interface calls are kept intact, then write a new Dialogbuilder class, and let this class implement all the interfac
When compiling a program with GCC, parameters such as "-I" (uppercase I), "-l" (uppercase L), and "-l" (lowercase L) may be used, below is a record:
Example:
Gcc-O hello. C-I/home/Hello/include-L/home/Hello/lib-lworld
The above statement indicates that when compiling hello.

ConclusionLinklist *l and Linklist *lThe reference L is to change the value of L, and L points to the address of the head node of the list, that is, to change the address of the head node, but the general change chain is the node after the first node to operate, so the address of the head node has not changed, so remov

_ T ("") is a macro whose role is to allow your program to support Unicode encoding.Because Windows uses the ANSI and Unicode character sets,The former is the common single-byte mode,However, it is inconvenient to process double-byte characters such as Chinese characters in this way,It is easy to have half Chinese characters.The latter is in dubyte mode to facilitate the processing of dubyte characters.
All character-related functions of Windows NT provide two versions, while Windows 9x only sup

There are N casinos lined in a row.If Memory plays at casino I, him has probability pi to win and move to the casino on the right (i + 1) or exit the row (if i = n), and a probability 1-pi to lose with the casino on the left (i-1) or also exit the row (if I = 1).
We say that Memory dominates on the interval I ... j if he completes a walk such of that and he starts on casin
