style: unify backtick identifiers with existing solution math - #6273
Merged
Merged
Conversation
When a name is already written as math in the same solution, or appears on a complexity line, use that math form instead of a backtick. Also drop three duplicated 的 in solution prose.

🟡 Changes recommended
Identifier normalization incorrectly changes SQL and Lisp keywords and exact string literals to mathematical formatting across multiple READMEs, violating the documented distinction that preserves their backticks.
17 open issues
What changed in this PR
Standardizes mathematical identifier notation across Chinese and English solution documentation without changing executable solutions.
Changes:
- Replaces selected backticked identifiers with inline math.
- Updates algorithm explanations, Thinking blocks, and complexity annotations.
- Preserves problem statements and fenced code.

Summary
Solution prose often writes the same name both as
`nums`and as$\textit{nums}$. This pass keeps one form: if a solution already uses$\textit{...}$for a name, or the name appears on a time/space complexity line, the remaining pure-identifier backticks become math as well. Calls, indexed expressions, and keywords such astrue/falsestay in backticks. Three duplicated 「的」 in solution prose are removed (「上次出现的的位置」, 「一个字母的的情况」, 「最小值的的差值」).Problem statements and code fences are unchanged.
