The solution of optical drive not read disk
Computer optical drive due to often read disk friction, as well as some other reasons, will appear can not read the disk, the following for you to explain the CD drive does not read the possible causes and solutions!
If an optical drive does not read the disk, we first add electricity and put a genuine disc to see if the panel lights flashing, there is no "Tatsu, Da, da" sound, if there is, then we can conclude that the laser head and the main bear

Under what circumstances should we use "two items Heap "?
If Union operations are not supported, the data structure of a normal heap is an ideal data structure. However, if you want to support merge operations on a set, it is best to use two heaps or a Fibonacci heap. The worst case for a normal heap in a union operation is O (n ), but the two heap and the Fibonacci heap are O (lgn ).

Because there are only four squares, the order and placement direction (horizontal or vertical) of each square are enumerated. The placement method is only the six basic modes given by the question, calculate the minimum area in different modes and update the optimal solution.
4th and 5 are essentially the same ., The minimum area for different modes is as follows:
Set W1, W2, W3, and W4 to the horizontal length of the four
For small Web sites, using this does not bring a huge waste of resources, but if it is such a very large site like Yahoo, just need to have a choice of CSS reset to reduce resource waste.
Are you using CSS to reset with CSS? Of course, you may use it, but you do not know it is being used, such as you may often use: Program code * {padding:0; margin:0; border:0;} This is also a method of CSS reset, so that all the selectors padding, margin and border are set to 0.
