Interval Overlap → see Interval Overlap Predicate

Scope — Redirect only. This sheet was renamed to array_overlap_explanation.md in Nov 2026 to fix the misspelt filename; it exists to point old links at the right sections. See also: array_overlap_explanation.md — the canonical sheet for the interval-overlap predicate.

This sheet is now array_overlap_explanation.md.

Only the filename changed: explaination was a typo. The content moved as it was.
