Q: How can I slim down Windows 7 systems? A: remove the virtual memory file to a non-system disk. As we all know, Windows provides a virtual memory mechanism to speed up system running. In Windows 7, this function is enabled by default, and the virtual memory file is on the system disk. For example, for a machine with 2 GB memory, the virtual memory file size is 2 GB. We can completely remove the virtual

Question (test instructions): Describe a O (n LG (n))-time algorithm, given a set S of n integers and another integer x, determines whether or not th ere exist elements in S whose sum is exactly x. Design an O (n LG (n)) time complexity algorithm, given a set of n numbers, and a number x, asking if it is possible to find two numbers in this set, their and exactly X. Solution (Solution): In an array to find a certain number, O (n LG (n)), it is easy to think of sorting
