[2] NOI2017 integer problem statement, https://duck.ac/problem/noi17a, used only to confirm
    language/data bounds (n<=10^6, |a|<=10^9, b<=30n), no text reused.
Approach (this submission):
    Single-variable experiment on the champion chassis [1]: append #pragma GCC optimize(O3) overriding the chassis O2.
    All code, data and algorithms are unchanged; only the listed compiler setting differs.
Purpose:
    Price this compiler setting on the current online judge. Pre-registered criterion: stop
    the problem if the official reading meets the strict goal threshold (0.99*T+1us).

/* References: saffah_codex_6a_agg3 https://duck.ac/submission/129738 supplies the accepted peeled searches and proven ripple endpoints; all inherited author and license notices remain below. NOI2017 integer statement https://duck.ac/problem/noi17a supplies n<=10^6, |a|<=10^9, b<=30n and nonnegative intermediate values.
Idea: Every nonfull search starts at q+1 or q+2 with q<=floor(30n/32). The current integer is below n*10^9*2^(30n)<2^(30n+50), while the existing allocation covers at least 30n+128 bits. Thus a higher zero limb always exists before the allocated limit. Give only nonfull searches a success-only top-chunk scan and remove their unreachable missing-endpoint branch. Keep the nonempty search and its shared bounded helper unchanged, including preview failure recovery.
Purpose: Delete impossible nonfull top-level bounds checks without changing any bitmap, arithmetic, allocation, or empty-search behavior.
*/
/* References: saffah_codex_6a_agg3 https://duck.ac/submission/129732 supplies the accepted peeled-word searches and all inherited author/license notices below. Idea: retain that strongest engine and exploit the proven ripple endpoint preconditions: incBlock is reached only on a non-full block, decBlock only on a non-empty block. Decode only reachable word/block states, retaining the original arithmetic, pushChunk, assignments and summary writes. Purpose: combine eliminated search-loop work with the independent deletion of impossible endpoint branches. */
/* References: saffah_codex_6a_agg3 https://duck.ac/submission/129714 supplies the accepted parser and lazy integer hierarchy, including all inherited public credits and licenses below.
Idea: A nonfull/nonempty word bitmap certifies a candidate in every selected word. Only the current word can lose all candidates after discarding positions below p. Check that partial word once, then select at most one later complete word directly. Keep the same lazy uniform-word decoding, chunk search, and missing-candidate fallback.
Purpose: Delete the repeated current-word comparison and empty-result test from later words in carry/borrow search without changing bounds, representation, or arithmetic.
*/
/* References: saffah_codex_6a_agg3 https://duck.ac/submission/129696 supplies the complete accepted parser/integer engine, including the existing eight-byte digit-bit delimiter test; all original authors and licenses remain below. Idea: in the two nonnegative decimal fields parsed by parsePairF, every digit has ASCII bit4 set and each separating space/newline has it clear. Shift that bit into each byte sign position and invert the vector movemask to locate the same first two delimiters, preserving later decoding and all loads. Purpose: replace the compiler's compare-via-min/equality chain and constant operand with a single vector shift. */

actual-value unit parser and general engine; inherited citations retained below.
The statement https://duck.ac/problem/noi17a bounds b,k by30*n with n<=1000000.
Idea: After unit-magnitude specialization, every parseNumF caller reads only b
or k, at most30000000 (eight decimal digits). Remove its impossible ninth/tenth
digit continuation. General magnitudes still use parsePairF or the safe parser.
Purpose: Remove an extra branch and delimiter read on eight-digit shift/query
tokens using the exact limits of every remaining fast-reader call site.

https://duck.ac/submission/126120 established the unit-header parsing route;
https://duck.ac/submission/126126 retains actual single-digit values correctly.
The documented t1<=2 subtask in https://duck.ac/problem/noi17a has unit magnitude.
Idea: Use the header to select the one-digit path, but read its actual magnitude
instead of replacing it by1. In particular zero is preserved. This combines
the faster header dispatch with the actual-value handling of the accepted path.
Purpose: Avoid redundant paired decoding and per-update width checks on the
one-digit subtasks while maintaining the general parser elsewhere.

The statement https://duck.ac/problem/noi17a guarantees |a|=1 when t1<=2.
Idea: In that subtask, skip the known one-digit magnitude and its following
space after the existing sign check. Parse only b with the eight-digit reader;
the buffered update value remains exactly one. The general-A and offline
paths keep their established implementations.
Purpose: Avoid a redundant paired decimal conversion on the large unit-update
subtasks, using a documented input guarantee rather than guessing token values.

fixed-window paired parser, with all original citations retained below.
Idea: One immediate qword permutation [0,1,1,2] creates both byte windows
[0..15] and [8..23] directly from the existing AVX load, replacing three
extract/align/insert operations. The problem's shift<=30*n<=30000000 is always
at most eight digits, so the extra shift-length guard and its always-zero
upper decimal chunk reconstruction are unnecessary.
Purpose: Realize the fixed-window parser with one permutation and one guard.

Our diagnostic https://duck.ac/submission/126044 shows parsing consumes about
49% of the slowest test's existing parse/apply phase cycles.
Idea: For 7-to-10-digit magnitudes, the shift field fits inside input bytes8..23.
Construct that fixed window from the already loaded 32 bytes, independent of the
first delimiter, and use one combined32-byte shuffle-table row for both values.
This removes a delimiter-dependent input reload and one shuffle-table load.
Short magnitude or longer shift cases keep the previous general parser.
Purpose: Shorten the paired-decimal parser's dependent memory chain.

stage and digit-bit delimiter observation. No separate license declared.
Idea: Eight-or-fewer-digit token groups produce two <=9999 partials, so pack
them into signed16 lanes and finish with one madd instead of scalar extract,
multiply and addition. ASCII digits all have bit4 set while whitespace clears
it, allowing one complemented mask. Also finish all offline carries beyond the
highest touched bin, including concentrated-update carry chains.
Purpose: Reduce the query-token conversion dependency chain, preserving values.

Idea: For that guaranteed offline shape, accumulate each signed shifted update
into two neighboring signed 64-bit base-2^32 bins, then normalize carries once
in one forward pass before answering queries directly from the final words.
Split the signed shifted amount into its unsigned low word and arithmetic high
word; at most one million updates keep both accumulation bins within int64.
