Bit-xor clojure

I am trying to write a clojure code which generates an Image with each pixel of image having a value of XOR of its x and y co-ordinates but I am getting a NullpointerException.

Each bit of the output is the same as the corresponding bit in x if that bit in y is 0, and it's the complement of the bit in x if that bit in y is 1.

4 Aug 2012 Anyway, suppose we want a similar macro that provides the XOR function (which isn't yet in Clojure core)? How should be. with xor it helps to think of xor as “bit parity” – with an even number of set bits in the inp

This member function allows the object to be used with the same syntax as a function call. Clojure metadata is stored with a value which is an instance of clojure.lang.IObj. Many types are subclasses of clojure.lang.IObj, but integers, floats, and strings are not. Clojure metadata is immutable: all keys must be set at once and there is no way to remove keys.

- Clojure.plist The encryption would perform a bit XOR of every byte from message array with a corresponding byte from the key array. Since the key is shorter than the message, when the key's index will go out of bounds, it should be started from the beginning again.

I am trying to write a clojure code which generates an Image with each pixel of image having a value of XOR of its x and y co-ordinates but I am getting a NullpointerException.

Output 576 37441 36865 clojure_operators.htm In the process of doing this, I was struck by all the bit-functions — of the ~600 vars and functions in clojure.core, there are 12 specifically for bitwise operations.

I am trying to write a clojure code which generates an Image with each pixel of image having a value of XOR of its x and y co-ordinates but I am getting a NullpointerException. I am not able to figure out what is going wrong in my code. Here is my code:

I decided to find the way by myself and finally found a way to enumerate the macros of cljs.core in Clojure REPL, so I want to share the exprerience with others here. Example int a = 5; // 0101b (0x05) int b = 9; // 1001b (0x09) int c = a ^ b; // 1100b (0x0C) std::cout << "a = " << a << ", b = " << b << ", c = " << c << std::endl; Clojure Strengths re: Cryptology.
