This problem remind me of HITCON CTF 2014 -- 24

The server gave us 5 numbers v1, v2, v3, v4 & v5, and ask us to use +, -, *, /, ( & ) to do some operation with v1, v2, v3 & v4, and make it equal to v5

The solution is pretty simple: since it gave us a lot of time to solve a round, we can easily beat the challenge by brute-forcing all the possible combinations of operators & operands
