Assume we are dealing with an environment which could only store integers within the 32-bit signed integer range: [−231, 231 − 1]. For the purpose of this problem, assume that your function returns 0 when the reversed integer overflows. 给出一个 32 位的有符号整数,你需要将这个整数中...

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. ...
