Reused the latest NOIP17f solution, including its dense RCNT indexing and
inherited parser/queue citations, preserved below. No separate license declared.
Idea: Resolve small rows with zero or one previous deletion directly. For
one deletion at p, selecting rank k is exactly k+(p<=k), so no fixed-point
iteration or repeated count is needed. Finish the pair parser with packed signed-16 narrowing (four-digit
intermediates are <=9999) and one pmaddwd, replacing pmulld plus phaddd.
Remove the ten inline-assembly loads whose value is discarded each query.
Purpose: Verify equivalent queue results and recover the dynamically tightened
online runtime target through reduced instructions and dependency latency.

// 【n17b_ 席 · 相位 2（行扫描）单变量：把"每行计数"改成**按下标（偏移）索引** ⇒ 随机写变顺序写】
// 改动（两行，见正文 `RCNT[off - c] = c;` 与组路径的 `RCNT[base]`）：
//   相位 2 原本对每个有状态行写 `RCNT[r] = c`（r 随机 ⇒ 7.9 万次 1.2 MB 数组的**随机写**）；
//   但组路径读它时用的下标是 `base = (RC[r] & RC_MASK) - 1`，**就是该行的偏移 ob**，而相位 2 里
//   `ob` 随 r 单调递增 ⇒ 改成 `RCNT[off - c] = c` 后，写地址随 r 单调推进（相邻写相隔约 c≤8 个
//   u32 = 同一缓存行内）⇒ 随机写变**顺序写**；组路径读端同步改成 `RCNT[base]`，**取值逐位相同**。
// 逐位等价论证：写端 `off - c` == 读端 `base`（`RC[r]` 在此处正是 `ob + 1`，故 `base == ob`）；
//   偏移在相位 2 中两两不同 ⇒ 不覆盖；其余（RCNT 只在这两处被访问）不变。
// 闸门（本机，判题机形状引擎 + drv）：14 份输入逐字节同 md5 —— 5 形状×大尺度 + rand 六尺度
//   + **三份组路径输入**（rand 20/40×m=3e5 与 randx1 20×1e5，nbig≥8 且 4·XSW≥q ⇒ GROUPMODE=1，
//   即被改的组路径**确实被执行**）；并做**负控**：把读端故意改成 `RCNT[base+1]` ⇒ 组路径输入立刻
//   变 md5（5e9bb347…）而对照件相同 ⇒ 闸门对被改路径**敏感**（不是空跑）✓
// 相位尺（本机 PTICK，官方形 n=m=q=3e5 随机，交错 min-of-6×3 批）：相位 2 = 3.47 M → **2.99 M 拍**
//   （−13.5%，两批分离清晰）；同批 LOOP 相位两件不分离（43.7~44.0 M 拍）⇒ 未伤主环。
//   按本窗标定（判题机 0.674678 ms ↔ 本机 4.63 M 拍 ≈ 0.146 ms/M 拍）⇒ 预期 **−73 µs** 量级。
// 目的：把这一处**逐位等价**的顺序化收益兑现成判题机读数，作为本席交付的第二件。

Reused the online fastest solution, including deleted-bitset rank selection,
small-row handling, decimal output, and the original attribution comments below.
No separate license declared by its public source. All prior citations retained.
Idea: Replace the two separate SWAR integer decodes and shape checks in the
query-line parser with one delimiter mask and a length-pair shuffle, followed
by packed multiply-adds that decode both values simultaneously. Input lines
follow the stated x-space-y-newline shape and each number is at most 6 digits.
Disable the unused phase profiling timestamps.
Purpose: Verify correctness and measure whether less parser dependency work
reduces the online runtime by the required amount.

//   · 相位 2 = **5.33~6.35 M 拍**（占全时 ≈ 8%，量级 ≥0.512 ms 判据）· 相位 1 ≈ 16~21 M · 主环 ≈ 54~60 M
//   · 该相位的节奏**由两个数据相关分支决定**：`if(!c) continue`（本输入 63% 走 continue）与 `if(c==1)`；
//     而我们**只需要** `RC[r] ← (c>=2) ? off+1 : 0`（c==0 本来就是 0，c==1 要显式置 0）⇒ 整个决策是
//     **一条 cmov + 一条条件加**，不需要任何分支。
//   · 改后实测：相位 2 = **3.52~4.00 M 拍** ⇒ **−1.81 M 拍（−36%）**，相位 1 与主环**不动**（同批对照）。

// Safety: only called when 16 bytes are readable at gip.  sep1 <= 7 and sep2 <= sep1+8 keep the
// second 8-byte read inside those 16 bytes.  Returns 0 (gip untouched) unless the line is
// exactly "<digits> <digits>\n", so any other whitespace layout falls back to rd().
