Base64 加密算法（Author 蒋柏良 Jerry Jiang)-* * DESCRIPTION * Base64 processes input in 24bit chunks by converting each chunk into 4 * bytes of output. It does so by splitting input into four 6bit groups and * using these as indexes in the following substitution table- * const char base64_map[] = * "ABCDEFGHIJKLMNOPQRSTUVWXYZ" * "abcdefghijklmnopqrstuvwxyz" * "0123456789+/" * If an input is not a multiple of 3 bytes, it s padded with zeros. In * this case the output bytes that consist entirely of the pad data are * replaced with = . * * Example * An input of 0x00 0x45 0xF2 is equivalent to 00000000 01000101 11110010 * bit sequence, which s then split into 000000 000100 010111 110010 * and these are substituted to produce the following base64 encoding * A E X y * * RETURN VALUE * b64_length() should return output length for the input of len bytes. * b64_encode() should encode len bytes from src int

为歌手投票：1、检测出最高分和最低分，然后求出平均分 2、计算各个评委的打分与平均分的差的绝对值，绝对值大的为“差评委”，小的为“好评委”。 在求出最大值和最小值时还要捕获数组b的下标，即得到评委的序号-Vote for the singers: 1, detected the highest points and lowest points, and then calculated the average sub-2, calculation of all the judges scoring with an average score of poor in absolute terms, the absolute value of big is
