ProblemTest instructionsThe F and M two letters are composed of strings, FMF and FFF, which are unsafe strings, and now have 2*l letters asking how many secure strings you have. Answer mod M.AnalysisRecursive, the problem is intended to use a matrix fast power. However, I found this problem is very magical, as long as the appropriate reduction in the number of modules, you can water past (ha ha).At that time to do this problem with a rather strange recursion, and then timed out, but two two to p
allocation is the a+100 start.Memory Mapped file is not the same, from the above figure can be seen that MMF did not call the virtual series function. It calls the kernel layer directly.For malloc and new, these 2 are not operating system APIs, they are language-provided functions. There are different implementations on different systems, and on Windows, new calls the Malloc,malloc call heap function (HEAPXXX). The heap function calls the virtual ser
