Recall that the permutation is an array consisting of n distinct integers from 1 to n in arbitrary order. For example, [2,3,1,5,4] is a permutation, but [1,2,2] is not a permutation (2 appears twice in the array) and [1,3,4] is also not a permutation (n=3 but there is ...
char *GetString2(void) { char *p = 'hello world'; return p; } void Test5(void) { char *str = NULL; str = GetString2(); cout<< str << endl; } 函数Test5运行虽然不会出错,但是函数GetString2的设计概念却是错误的。因为GetString2内的“hello world”是常量字符串,位于静态存储区,它在...
这种中介vector叫做permutation vector。相似的,你也可以用标准的maps, priority queues, heaps, hash tables等等。 1.2.8 Code Inspection 如果你严格遵照资源管理的条款,你就不会再资源泄露或者两次删除的地方遇到麻烦。你也降低了访问野指针的几率。同样的,遵循原有的规则,用delete删除用new申请的德指针,不要两次...
