Question: Ideas Method 1: determine each substring of a string. If it is symmetric, obtain its length. This method is used to determine whether a substring is a substring from both ends to the middle. The total time complexity is O (n ^ 3 ), The time complexity is O (n ^ 2. Method 2: opposite to the method, each start in the string is extended to both sides, which can be divided into two situations: (1) When the length of a symmetric substring is an odd number, the current character is used as t

number from the last ugly number, and not need to start from 1 to iterate and judge. the 10 ugly numbers starting from 1 were 1, 2. 3,4,5,6,8. 9. 10. 12. Can be found in addition to 1. The number of ugly is from some ugly number * * or * * or to get the.If 2 is ugly number 1*2 get, 3 is ugly number 1*3 get. 4 is the ugly number 1*4 get. 5 is the ugly number 1*5 get. 6 is the ugly number 2*3 get ...Detailed algorithm steps:(1) Starting from the first ugly number 1, find out 1*2=2, 1*3=3, 1*5 = 5

Looking at Ching see from the Erlang processAfter the multi-core slowly fire, the co-process class programming also began to become more and more fire. There are more representative goroutine of Go, Erlang in Erlang, Scala actor, fibre under Windows, and some dynamic languages like Python, Ruby, and Lua are also slowly supporting the process.In fact, we have heard a lot about the association of many nouns, the following roughly to explain: OS

seen the built-in list, the tuple, and so on. They are easy to use. In Python's standard library, there are a number of objects that can be used for operating system interaction, Internet development, multi-threading, and text processing. And on top of all of these, there are a lot of external libraries that define richer objects such as NumPy, Tkinter, Django, etc. for scientific computing, GUI development, web development libraries, and a wide variety of objects. For the average user, it's mu

The company's servers are Linux, there is no way, you have to understand the system. Haha, these days apart from overtime is charged.

Although colleagues and I said they met will not go to Baidu, but Linux seems to do a bad job.They forget the difficulties of beginners, especially my non-computer majors.But brother Bird's handwriting
