In Bikini Bottom, there exists a special type of electronic lock.
This type of lock requires the user to key in 4 prime numbers to unlock.
However, the company that makes the lock has lost the program used to check whether the code is correct or not.
As such, you are tasked with writing a program to check whether all 4 numbers are prime.
4 numbers representing the 4 numbers the user keys into the electronic lock.
For 50% of the test cases, all 4 numbers are below 10000.
For 100% of the test cases, all 4 numbers are below 100000000.
Output "Opening..." if all 4 numbers are prime.
Output "Wrong code" if not all 4 numbers are prime.
