优化代码： int num[LED_NUMBER]={ a4[8],a4[9],a4[10],a4[11],a4[12],a4[13],a4[14],a4[15], a3[8],a3[9],a3[10],a3[11],a3[12],a3[13],a3[14],a3[15], a2[8],a2[9],a2[10],a2[11],a2[12],a2[13],a2[14],a2[15], a1[8],a1[9],a1[10],a1[11],a1[12],a1[13],a1[14],a1[15], a1[0],a1[1],a1[2],a1[3],a1[4],a1[5],a1[6],a1[7], a2[0],a2[1],a2[2],a2[3],a2[4],a2[5],a2[6],a2[7], a3[0],a3[1],a3[2],a3[3],a3[4],a3[5],a3[6],a3[7], a4[0],a4[1],a4[2],a4[3],a4[4],a4[5],a4[6],a4[7], a1[23],a1[22],a1[21],a1[20],a1[19],a1[18],a1[17],a1[16], a2[23],a2[22],a2[21],a2[20],a2[19],a2[18],a2[17],a2[16], a3[23],a3[22],a3[21],a3[20],a3[19],a3[18],a3[17],a3[16], a4[23],a4[22],a4[21],a4[20],a4[19],a4[18],a4[17],a4[16], a4[24],a4[25],a4[26],a4[27],a4[28],a4[29],a4[30],a4[31], a3[24],a3[25],a3[26],a3[27],a3[28],a3[29],a3[30],a3[31], a2[24],a2[25],a2[26],a2[27],a2[28],a2[29],a2[30],a2[31], a1[24],a1[25],a1[26],a1[27],a1[28],a1[29],a1[30],a1[31], a4[40],a4[41],a4[42],a4[43],a4[44],a4[45],a4[46],a4[47], a3[40],a3[41],a3[42],a3[43],a3[44],a3[45],a3[46],a3[47], a2[40],a2[41],a2[42],a2[43],a2[44],a2[45],a2[46],a2[47], a1[40],a1[41],a1[42],a1[43],a1[44],a1[45],a1[46],a1[47], a1[39],a1[38],a1[37],a1[36],a1[35],a1[34],a1[33],a1[32], a2[39],a2[38],a2[37],a2[36],a2[35],a2[34],a2[33],a2[32], a3[39],a3[38],a3[37],a3[36],a3[35],a3[34],a3[33],a3[32], a4[39],a4[38],a4[37],a4[36],a4[35],a4[34],a4[33],a4[32], a1[55],a1[54],a1[53],a1[52],a1[51],a1[50],a1[49],a1[48], a2[55],a2[54],a2[53],a2[52],a2[51],a2[50],a2[49],a2[48], a3[55],a3[54],a3[53],a3[52],a3[51],a3[50],a3[49],a3[48], a4[55],a4[54],a4[53],a4[52],a4[51],a4[50],a4[49],a4[48], a4[56],a4[57],a4[58],a4[59],a4[60],a4[61],a4[62],a4[63], a3[56],a3[57],a3[58],a3[59],a3[60],a3[61],a3[62],a3[63], a2[56],a2[57],a2[58],a2[59],a2[60],a2[61],a2[62],a2[63], a1[56],a1[57],a1[58],a1[59],a1[60],a1[61],a1[62],a1[63], };

可以使用循环来优化代码，将数组中的元素逐个赋值给num数组。具体实现如下：

int idx = 0;
for (int i = 8; i <= 15; i++) {
    num[idx++] = a4[i];
    num[idx++] = a3[i];
    num[idx++] = a2[i];
    num[idx++] = a1[i];
}
for (int i = 0; i <= 7; i++) {
    num[idx++] = a1[i];
    num[idx++] = a2[i];
    num[idx++] = a3[i];
    num[idx++] = a4[i];
}
for (int i = 23; i >= 16; i--) {
    num[idx++] = a1[i];
    num[idx++] = a2[i];
    num[idx++] = a3[i];
    num[idx++] = a4[i];
}
for (int i = 24; i <= 31; i++) {
    num[idx++] = a4[i];
    num[idx++] = a3[i];
    num[idx++] = a2[i];
    num[idx++] = a1[i];
}
for (int i = 40; i <= 47; i++) {
    num[idx++] = a4[i];
    num[idx++] = a3[i];
    num[idx++] = a2[i];
    num[idx++] = a1[i];
}
for (int i = 39; i >= 32; i--) {
    num[idx++] = a1[i];
    num[idx++] = a2[i];
    num[idx++] = a3[i];
    num[idx++] = a4[i];
}
for (int i = 55; i <= 63; i++) {
    num[idx++] = a4[i];
    num[idx++] = a3[i];
    num[idx++] = a2[i];
    num[idx++] = a1[i];
}
for (int i = 56; i <= 63; i++) {
    num[idx++] = a4[i];
    num[idx++] = a3[i];
    num[idx++] = a2[i];
    num[idx++] = a1[i];
}

这样代码更清晰，易于维护和修改。同时，也减少了代码的重复性。
