I have a large bitset that I want to frequently reset individual bits in it. Which method is faster? a) bitset[word_index] ^= 1 << bit_index
So with the help of you guys I finished creating my very simple image encrypter. It\'s enough to keep any non-tech person out, right? :P
//key & hash are both byte[] int leftPos = 0, rightPos = 31; while(leftPos < 16) { //possible loss of precision. required: byte, found: int
Why does the statement z ^= true produce a false when the previous produces a true ? bool v = true; bool z = false;
I need to port s开发者_运维百科ome JS code which involves Math.random()*2147483648)^(new Date).getTime(). While it looks like for smaller numbers, the python function and the JS function are equivalen
Thanks to pbos help and its program (published here, for xoring a big file), I performed some tests and I see that I have another problem: having开发者_如何学Python changed the mask by another one of
I would like to XOR a very big file (~50 Go). More precisely, I would like to do so by XORing each block of 32 bytes of a plaintext file (because of lack of memory) with the key 3847611839 and create
这篇博客将介绍如何使用OpenCV应用按位AND、OR、XOR和NOT。上一篇学习了如何从图像中裁剪和提取感兴趣的区域（ROI），截取的都是矩形。但是如果想裁剪一个非矩形区域呢？该怎么办？答案是同时应...
