1.1.1 Remove Duplicates from Sorted Array题目： Given a sorted array, remove the duplicates in place such that each element appear onlyonceand return the new length. Do not allocate extra space for another array, you must do this in place with constant memory. For example, Given input array A =[1,1,2],Your function should return length =2, and A is now[1,2]. 分析： 时间复杂度 O(n)，空间复杂度 O(1)，因为是排好序的。后一个和前一个比较，相同则不要（

The shell may often see: >/dev/null 2>1 The result of the command can be defined as the output in the form of%> /dev/null represents empty device files > represents where to redirect, for example: echo "123" >/home/123.txt 1 indicates stdout standard output, the system default is 1, so ">/dev/null" is equivalent

Level 1 cache, level 2 cache, and lazy loading (transfer) in Hibernate, and level 1 cache in hibernate1. Why cache? Hibernate uses cache to reduce the number of accesses to the database, thus improving the execution efficiency of hibernate. There are two types of cache in hibernate: level-1 cache and level-

Shell may often see:>/dev/null 2> 1 Command results can be defined in the form of %> /Dev/null indicates an empty device file.> Indicates the redirection location, for example, echo "123">/home/123.txt1 indicates stdout standard output. The default value is 1. Therefore, ">/dev/null" is equivalent to "1>/dev/null"

Case has two formats. Simple Case functions and Case search functions. Case has two formats. Simple Case functions and Case search functions. The Code is as follows: -- Simple Case Function CASE sex WHEN '1' THEN 'male' WHEN '2' THEN 'female' ELSE 'others' END -- Case search function Case when sex = '1' THEN 'male' WHEN sex = '
