首先执行reverseString("abc"),这时候传入的str不为空,所以执行else部分。读到了reverseString(str.substr(1)),这时候就是递归调用,执行这段代码,其中str.substr(1)为"bc" reverseString("bc"),这时候传入的str不为空,所以执行reverseString(str.substr(1)),其中str.substr(1)为"c" reverseString("c"),这...
A sequence of non-space characters constitutes a word. Could the input string contain leading or trailing spaces? Yes. However, your reversed string should not contain leading or trailing spaces. How about multiple spaces between two words? Reduce them to a single space in the reversed string. ...
AI代码解释 voidreverseWords(string&s){string ss;int i=s.length()-1;while(i>=0){while(i>=0&&s[i]==' ')//处理多个空格的情况{i--;}if(i<0)break;if(ss.length()!=0)ss.push_back(' ');string temp;for(;i>=0&&s[i]!=' ';i--)temp.push_back(s[i]);reverse(temp.begin()...

第一道题,题目提示非常简单的逆向并提供一个 zip 压缩包,下载本地解压后是一个 exe 可执行文件。尝试用 IDA 反编译,发现 flag 出来了。 感谢善待新人 reverse1 依然给了一个压缩文件,解压后依然是一个 exe 可执行文件,再次尝试用 IDA 反编译,这次没有一眼看到 flag 了,甚至连主函数都没有。于是 Shift +...

In fact, this is probably the most utilized technique in cracking, the only competition would be a referenced text string search. This is why breakpoint checks are done over important APIs like MessageBox, VirtualAlloc, CreateDialog, and others that play an important role in the protecting user...
