Problem DescriptionThe greatest common divisor GCD (a, B) of two positive integers a and B, sometimes written (a, B), is the largest divisor common to a and B, For example, (1, 2) = 1, (12, 18) = 6.(A, B) can be easily found by the Euclidean algorithm. Now Carp is considering a little more difficult problem:Given integers N and M, how many integer X satisfies

First, look at what the Hyper-threading conceptHyper-Threading technology is the use of special hardware instructions, the two logical core simulation into two physical chips, so that a single processor can use thread-level parallel computing, and thus compatible with multi-threaded operating systems and software, reduce the idle time of the CPU, improve the efficiency of the CPU.Hyper-Threading Technology is a CPU executing multiple programs at the same time to share a CPU resources, in theory,
Title Description: Write the program, the output string of uppercase letters, lowercase small mother and the number of other. If there is a string "Helle, this is A test textfile.123456, Tannk you!!", the number of uppercase letters: 3, lowercase letters: 29, the number of other characters: 18.Here are four algorithms, the first of which is a good understanding,
