Using IDA,
```
int __cdecl main(int argc, const char **argv, const char **envp)
{
int v4; // [rsp+Ch] [rbp-4h]

puts("enter a number");
__isoc99_scanf("%d", &v4;;
if ( (unsigned int)get_number() == v4 )
{
puts("great number ,I like it.\ntake your price");
get_flag();
}
else
{
puts("sorry! I don't like this number\nTry again");
}
return 0;
}

There is a get_number Func.

signed __int64 get_number()
{
return 1139440753LL;
}

```

just enter the number...

IDK why this is pwn challenge lol
