已知肖像照片是64x64像素的0~255级灰度图片,内存中用raw bitmap方式,每个像素用一个字节存储。对肖像照片的原始数据,学生使用的加密代码片段如下(Python3代码,代码中的key值是未知的加密密钥):
_KEY_LEN = 2 bitmap = PIL.Image.open(image_path).tobytes() encrypted = [] for index, byte in enumerate(bitmap): encrypted.append(byte ^ key[index % _KEY_LEN]) return base64.standard_b64encode(bytes(encrypted))(1)请问:这张被加密的照片,是以下哪位图灵奖得主的肖像?
(A) Marvin Minsky
(B) John L. Hennessy
(C) Donald E. Knuth
(D) Raj Reddy
