Given an absolute path for a file (Unix-style), simplify it. For example,path = "/home/", => "/home"path = "/a/./b/../../c/", => "/c" Corner Cases: Did you consider the case where path = "/../"?In th…

原题地址 用栈保存化简后的路径.把原始路径根据"/"切分成若干小段,然后依次遍历 若当前小段是"..",弹栈 若当前小段是".",什么也不做 否则,入栈 代码: string simplifyPath(string path) { vector<string> buffer; char *tok = NULL; tok = strtok((char *) path.c_str(), "/"); while (tok…
