When the physical memory is not enough, the temporary unused data is temporarily put into the virtual memory of the hard disk, the best way to reduce PF is to increase the memory.　　Reasons for PF Increase:1. Physical memory is too small2. Startup program is too large3. Virtual memory settings are unreasonableTo modify v

PHP as PHP script processing. 8. Statements include and require can include another file in the current file, the difference is (12), in order to avoid multiple inclusion of the same file, you can use the statement (13) instead of them. 9. The properties of the class can be serialized and saved to the session so that the entire class can be restored later, and the function to be used is (14). 10. The argument of a function cannot be a reference to a variable unless (15) is set to on in PHP.ini.

From: http://blog.csdn.net/wodewe/article/details/6863753 # Question: There are n + 2 numbers, N numbers appear even, and 2 numbers appear odd (these two numbers are not equal). The space complexity of O (1) is used, find the two numbers. You do not need to know the specific position. You only need to know the two values.Solution: if there is only one number that has exceeded an odd number, it is better to solve the problem. The elements in the array are exclusive orThe number that appears
