Strega
Week 1
Alright boys and girls. This is an easy one. It's so easy, but I'll still give you all a hint. It can be solved without the hint but if you understand the hint, you can solve it easier

Decipher this;

APZAWP DSZFWO DEZA HLDETYR XZYPJ LYO CPDZFCNPD ZY HLC PBFTAXPYED


Hint;

x--f--> Ax+c

4--f--> -4

2--f--> 4

The solution to this is in the comment.

APZAWP DSZFWO DEZA HLDETYR XZYPJ LYO CPDZFCNPD ZY HLC PBFTAXPYED is a Caesar ciphertext. A Caesar cryptogram works like code rings you get from cereal boxes. You know, the ones which use the cipher wheel. The one with two cyclic circles which can be rotated. An example of a cipher wheel;

This is how you use the hint;
f(x) = Ax+c
f(2) = 4
2A+c = 4----> ♥(just a symbol which can be replaced by anything)
f(4) = -4
4A+c = -4----> ♣
♣ - ♥, ----> 4A+c
-(2A+c)
2A = -8
A = -4
Substitute A = -4 into ♥, you'll get -8+c = 4
c = 12

So, the first letter is 12. 12 = L in alphabetical arrangement. The first letter in English is A. So, A = L
Spin the wheel till you get A = L. You may have to do trial and error for once because when you spin and get A = L, you may have the wrong wheel. It's either A = L or L = A. From the figure above, you can see that A = T when you read from outer to inner while A = H when you read it from the inner to outer. With all these known, the answer is pretty much there.

The answer is PEOPLESHOULDSTOPWASTINGMONEYANDRESOURCESONWAREQUIPMENTS. People should stop wasting money and resources on war equipments. Obama as the president of the US is one of those( there are a lot more ) who should read this. Seriously, rather than building missiles and tanks, the money should be used to stop the recession.
