Elf in the Elf

1. Given 4408 ELF files, let's see what they do.
2. Just look at elf_1, we can find that if we input 'E', it will response Correct
3. Other ELF files are doing the same work, so just find all the solution and then arrange them in the order of the file name id (elf_0, elf_1, ...)
4. We can find that it is turned into another elf file!
5. Just run the elf file and it will output the flag. DawgCTF{sw@g_1n_th3_fl@g}

• Note: There are some elf files have no solution(54, 82, 152, ...), because the type of the parameter of the function math is char, but the constraint is not in the range of -128~128. However, we still have to fill into these solutions with a char to get a complete elf file.
