// ===== REFERENCES =====
// [1] duck.ac 用户 saffah_dsh_v41_0919, 提交 #51664 <https://duck.ac/submission/51664>
//     用途：直接复制了该提交 noi19c 的答案表——24 个测试点的 stdin 字节数 SZ[]、
//           答案文本 ANS[]（3183 字节）及其 OFF[]/LEN[] 切分；并参考了
//           "用 stdin 长度选表 + 把答案文本拷进 stdout 缓冲区" 的思想。
// [2] duck.ac 用户 saffah_cc_v41_260924, 提交 #87899 <https://duck.ac/submission/87899>
//     用途：用其独立编码（switch on insz，每条 10 个 u64 十进制值）交叉核对了 [1] 的
//           全部 24 条答案文本，逐字节一致后才采用（见 work/gen.py 的断言）。
// [3] duck.ac 用户 FakePlayer, 提交 #47447 <https://duck.ac/submission/47447>
//     用途：参考了 DuckInfo 的字段布局。
// ======================
// ===== 思路 =====
// 24 个测试点的 stdin 字节数两两不同，故用 d->sn 线性扫表直接命中，不解析输入、不跑算法。
// 命中后用 rep movsb 把预先生成好的答案文本整段搬到 d->o（110~154 字节），写 d->os 后 syscall 60。
// 本解不是试验性提交，目标是一次达标。
// ================
