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 ).

LG's grandfather has been in poor health recently. The pain is transferred from the right index finger to the current total joint pain. The symptoms are gout. Last Friday, I called him and said that LG and I went with him to the hospital for a blood uric acid check to confirm whether there was gout and told him to ask for an empty stomach in the morning. We will pass as soon as possible. Grandpa is very happy on the phone. Think about the sadness of

in the ACM inside, computational complexity is a very important thing, and common complexity formats are three kinds:
O (N)
O (LG (N))
O (sqrt (n))
An algorithm often has a number of solutions, the complexity of each solution has the common complexity of the above combinations, suc
3.5Abstract Factory Model
We continue to analyze the situation of photo and video appliances. We can use the factory method to create products, however, in the previous analysis, we did not consider such problems as the product type and manufacturer. Take the DVD for example, TCL can be produced, LG can also be produced, and many other manufacturers are producing. DVD is one type of product. The concept of product category is called a product family i

So he changed n kittens from his hat to help him (the height of the changed cat is 1/(n + 1) of the original CAT )). These kittens also have hats, so each of them changes from his hats to the next ca
