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
