// ======================
// ===== 思路 =====
// 【口径】`tools/exact.py noi17e`（开工时）：mine = **7.551047**（#108505）
// · T = **7.496481**（#108690，**晚于**我方 #108505 提交 ⇒ 表面落在宽支 7.534963）
// · ★ **交件可达线 = 严支 0.99*T + 1µs = 7.422516** —— 只要我方提交一件比现役最好更快的，
// 本账号的「最快提交」就变成最新的那件 ⇒ T 变"更早" ⇒ 判据立刻切到严支
// （`BRIEF §2.19.1029` 宽支陷阱）⇒ **真门槛 = −128.531 µs = −1.702%**。
// 【本发 = 对手 #108690 相对我方 #108505 的全部 delta，共 2 项】
// ① **`[XFAST]` 直读行末的 `x`**：`x = rd()` → `x = (u32)(gip[1] - '0'); gip += 2;`
// —— 输入每行四元组 `a s c x` 的最后一个字段在本域内**恒为单个数字**：本引擎自己就把 x
// 压进 **3 bit** 字段（`VK[i] = c | (x << 17)`，x ≤ 7），所以"单字符"不是新假设，而是引擎
// 已有的域不变量；`rd()` 少调用 1/4 ⇒ 省掉它的空白跳过 + 位数循环 + 指针回写。
// 【判题机定价】`work/n17w_probe.py`（同二进制多臂原位探针，见下）：
// **Xfast = 18 429 484 vs base = 18 649 752 周期 = −220 268 = −1.181%**（parse 相位 −3.0%）。
// ② **`[MONE]` 把"每天配额 = 1"做成编译期常量**：把天循环整体包成一个 `dayrun(auto tag)` lambda，
// `constexpr bool MONE = decltype(tag)::value;`，只把 `quota` 与 `take` 两处改成
// `MONE ? 1 : ...`，然后 `if (m == 1) dayrun(std::true_type{}); else dayrun(std::false_type{});`
// ⇒ m==1 时 `quota`/`take` 变成常量 1，`while (rk >= 0 && quota > 0)` 与 `if (quota <= 0) break;`
// 整条被折掉（本题数据里 m=1 常见 ⇒ 这正是对手给这道题选的专门化）。
// ★ **本发不做单变量拆分**：两项都是对手**已 Accepted 的同一个包**，属"整包移植"口径
// （与上一席 ① ② ③ 打包移植同例）。
// 【正确性闸门（本地，提交前）】`g++ -O2 -static -U_FORTIFY_SOURCE -std=c++17` 编译通过；
// `work/n17w_rand2.py`（域内随机差分，10 形态 × 60 例，逐元素比较，**含 m=1 且 x≠0 的形状**
// —— 正是 `[MONE]` 专门化与 `[XFAST]` 的覆盖面）⇒ **done: 60 cases, 0 failures** ✓
// （对照件 = 未改动的前一版最好件 `#108505`，它只有**通用**天循环 ⇒ 两个实例被直接对拍）。
// 【死读者复审（`§2.19.1089`：抄完之后必须看他留下了什么死码）】本题**无对象**：
// `grep prefetch` 全件只剩 2 条且都活着 —— ① radix 散射的目的行预取 `&dst[cnt[bb]]`
// （第 3 趟 scatter 的写目标）、② rank build 里的 `&VK[vf]`（下行要读）。对手这两项改动
// 也没有移除任何数组的最后一个读者。本轮据此**零改动**（已如实记录，省后人一发）。
// 【判题机原位探针（本轮建立，本题可复用）】`work/n17w_probe.py <engine> <out.cpp> [n m k xmax]`
// = 把各旋钮改成**运行期全局**、harness 内自带**确定性生成器**（不吃 stdin）、rdtscp 相位打点、
// 弃用热身臂、每臂 checksum + min-of-reps ⇒ 经 `tools/probe.py`（立即体验，≤1000 ms）在**判题机
// CPU 上**做同二进制 A/B。本题 A/A 噪声实测 **±0.07%**（base 18 649 752 ↔ base2 18 662 352）。

answer loop reloading `gob` from memory at the top of every iteration and writing
it back at the end (`mov %rax,0x681600b(%rip) # gob`), i.e. a store->load chain
through the store buffer on EVERY answer, plus one load + one store per answer.
Here the cursor is a LOCAL threaded through the call (`op = wr64p(op, v)`), so the
loop carries one register and `gob` is touched once.
The digit path is unchanged except that the fast branch now also covers
[1e16, 1e20): split v = q*1e16 + r, emit q's 1..4 digits and r's 16 zero-padded
digits through the same 4xGT4 machinery, so no `lzcnt`/POW10/divide-loop is needed
