Description

Return missing numbers between min/max, distinct repeated page values in first encounter order and whether the original list is strictly increasing.

Administrative records depend on literal identifiers, numbering conventions, check alphabets and ownership mappings. A duplicate count, check symbol or one-hop route helps reconcile metadata without authenticating a document or establishing who has authority over it. A well-formed label can still refer to the wrong record.

Return missing numbers between min/max, distinct repeated page values in first encounter order and whether the original list is strictly increasing.

When to use this tool

Use Case File Page Number Continuity Gap when checking the stated administrative key, numbering, continuity or routing convention.

How to use the tool and how it works

  1. Enter pages. Use the units and conventions below.
  2. Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
  3. Read missing, duplicatePages, ordered. Inspect ordered before interpreting the associated values.

Require a nonempty list of whole page numbers>=1 spanning no more than 255. Return missing numbers between min/max, distinct repeated page values in first encounter order and whether the original list is strictly increasing.1

Limitations and assumptions

  • Missing pages outside the supplied min/max are invisible; the tool does not authenticate a case file or verify its contents.
  • Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.

Alternative or Complementary methods

Use authoritative source records and the complete applicable document/process scheme for actual identity, routing or integrity decisions.
