From the previous analysis, we already know that in Linux, there are two types of modules: internal modules and external modules. What we're saying here about target modules is to compile those internal modules, and the processing of the external modules will be described later. We also know that both internal and external modules are compiled in two phases. Stages of life into modules of the corresponding. o files

, when the side length is (a, B), a total of (N'-a) * (N'-B) * (gcd (a, B)-1) is invalid. However, because the range of N is too large, the length of the enumeration side is O (n ^ 2) Time-out. Therefore, we need to optimize the solution process:
The specific method is to enumerate the GCD value. Because the GCD value is at least 2, it will affect the result. Therefore, the GCD value can be enumerated from 2 and the maximum GCD value is n. If the enumerated GCD value is K, then if there is gcd

, and the modulus (the amount of "overflow") is 12. Now we move the hour hand counterclockwise from 4 to 2, and move clockwise 10 to get the same result. The arithmetic formula is 4-2 and 4+10, at a glance 4-2 is obviously not equal to 4+10, then why the two results on the clock is the same?That's "modulo" in mischief. When the result of the operation exceeds the counting range, the modulo operation is performed, and the 4+10=14>12,12 is 2=4+ (-2) after the modulo is obtained. At this point you
