What is APU The full name of APU is "Accelerated processing Units". The Chinese name is "Acceleration processor". The innovation of APU is to break the boundaries between CPU and GPU, and ultimately unify CPU and GPU from technology, production and application, in terms of structure, "obtain what is needed", "pay-as-you-go" on applications, and "merge into one" on products. But the performance of the two-in-one processors is simply 1 +

>>> and >> are bitwise operators, only valid for integral types (not for floating-point types).When the integer type (low+high) >>1 can replace (Low+high)/2.>>> is the unsigned right-shift operator. If Low+high is a positive integer, these three operations are equivalent.Because of compiler optimizations, their efficiency should be the same (if there is no compiler optimization, the shift operation is faste

Level 1 cache, level 2 cache, and lazy loading (transfer) in Hibernate, and level 1 cache in hibernate1. Why cache? Hibernate uses cache to reduce the number of accesses to the database, thus improving the execution efficiency of hibernate. There are two types of cache in hibernate: level-1 cache and level-

Problem 1: Carpet layingAt first glance, cry, carpet coverage... it seems to be a 2-dims line segment tree. It is so difficult at the beginning. Again, you only need to find a point, make a decisive question, and simulate it. (Note: From the enumeration with a large label to a small one, if there is a carpet that meets the requirements, the output will be returned .)(If the entire article is not completed,

male student named 8006, who has made countless friends. Recently, this student played a romantic game and wrote a letter to each of the N netizens. This is nothing, the worst thing is, he put all the messages in the wrong envelope! Note: It's all wrong! The question is: How many possible error methods are there for the poor 8006 students? The input data contains multiple test instances. Each test instance occupies one row and each row contains a positive integer of N (
