EBCDIC代码高尔夫(生日快乐,System / 360!)
自IBM推出System / 360系列计算机以来,已经有50年了。这些是第一个使用EBCDIC字符集的人。 为了纪念这种情况,让我们看看谁可以编写能够将“普通”文本与EBCDIC代码页037相互转换的最短程序。我们将使用维基百科的转换表,该转换表将CP037映射到ISO-8859-1的超集。: EBCDIC037_to_Latin1 = [ 0x00,0x01,0x02,0x03,0x9c,0x09,0x86,0x7f,0x97,0x8d,0x8e,0x0b,0x0c,0x0d,0x0e,0x0f, 0x10,0x11,0x12,0x13,0x9d,0x85,0x08,0x87,0x18,0x19,0x92,0x8f,0x1c,0x1d,0x1e,0x1f, 0x80,0x81,0x82,0x83,0x84,0x0a,0x17,0x1b,0x88,0x89,0x8a,0x8b,0x8c,0x05,0x06,0x07, 0x90,0x91,0x16,0x93,0x94,0x95,0x96,0x04,0x98,0x99,0x9a,0x9b,0x14,0x15,0x9e,0x1a, 0x20,0xa0,0xe2,0xe4,0xe0,0xe1,0xe3,0xe5,0xe7,0xf1,0xa2,0x2e,0x3c,0x28,0x2b,0x7c, 0x26,0xe9,0xea,0xeb,0xe8,0xed,0xee,0xef,0xec,0xdf,0x21,0x24,0x2a,0x29,0x3b,0xac, 0x2d,0x2f,0xc2,0xc4,0xc0,0xc1,0xc3,0xc5,0xc7,0xd1,0xa6,0x2c,0x25,0x5f,0x3e,0x3f, 0xf8,0xc9,0xca,0xcb,0xc8,0xcd,0xce,0xcf,0xcc,0x60,0x3a,0x23,0x40,0x27,0x3d,0x22, 0xd8,0x61,0x62,0x63,0x64,0x65,0x66,0x67,0x68,0x69,0xab,0xbb,0xf0,0xfd,0xfe,0xb1, 0xb0,0x6a,0x6b,0x6c,0x6d,0x6e,0x6f,0x70,0x71,0x72,0xaa,0xba,0xe6,0xb8,0xc6,0xa4, 0xb5,0x7e,0x73,0x74,0x75,0x76,0x77,0x78,0x79,0x7a,0xa1,0xbf,0xd0,0xdd,0xde,0xae, 0x5e,0xa3,0xa5,0xb7,0xa9,0xa7,0xb6,0xbc,0xbd,0xbe,0x5b,0x5d,0xaf,0xa8,0xb4,0xd7, 0x7b,0x41,0x42,0x43,0x44,0x45,0x46,0x47,0x48,0x49,0xad,0xf4,0xf6,0xf2,0xf3,0xf5, 0x7d,0x4a,0x4b,0x4c,0x4d,0x4e,0x4f,0x50,0x51,0x52,0xb9,0xfb,0xfc,0xf9,0xfa,0xff, 0x5c,0xf7,0x53,0x54,0x55,0x56,0x57,0x58,0x59,0x5a,0xb2,0xd4,0xd6,0xd2,0xd3,0xd5, 0x30,0x31,0x32,0x33,0x34,0x35,0x36,0x37,0x38,0x39,0xb3,0xdb,0xdc,0xd9,0xda,0x9f]; 规则: 您的程序应该接受两个输入:(a)一个文本字符串,和(b)一个指示要执行的操作的标志。 基于此标志,您的程序应将文本的每个字节转换为相应的EBCDIC字符,反之亦然。 可以从任何明智的来源(例如,命令行参数,stdin,键盘输入)获得输入,但不得将其硬编码到程序中。 输出应显示在屏幕上(例如,stdout,document.write)或写入文件/管道。 请勿使用任何内置或外部编码转换功能(iconv,等等)。 这是一个代码高尔夫球挑战,因此最短的答案(最小字节)将获胜。 例子: (注意:这些示例是在配置为使用UTF-8编码的终端中产生的。根据系统的配置方式,您可能会看到不同的结果。十六进制等效项仅供参考,不必由代码生成) Input: "HELLO WORLD", convert to EBCDIC Output: "ÈÅÓÓÖ@æÖÙÓÄ" (0xc8c5d3d3d640e6d6d9d3c4) Input: "ÈÅÓÓÖ@æÖÙÓÄ", convert from EBCDIC Output: "HELLO WORLD" Input: …
