一开始int temp 报错:Line 7: Char 15: runtime error: signed integer overflow: 964632435 * 10 cannot be represented in type 'int' (solution.cpp) 所以改成long temp = temp * 10 + x % 10;中间写的时候给加了个+=,可能就是感觉要自加,脑子比较混乱,不会颅内打码...

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 +...

Input file contains multiple test cases. There is a positive integer n (n<100) in the first line, which means the number of test cases, and then n 32-bit integers follow. Output For each test case, you should output its reverse number, one case per line. ...
DESCRIPTION The reverse_copy algorithm copies the range [first,last) to the range [result,result+ (last-first)) such that for any non- negative integeri< (last-first), the following assignment takes place: *(result+ (last-first) -i) = *(first+i) ...
