common-suffix

text →
common-suffix() → text

Returns the longest suffix shared by all accumulated strings.

Parameters

This accumulator has no parameters.

Behavior

Empty input returns null. A single string is returned unchanged. Nonempty input with no shared text, including an empty string, returns empty text. Comparison is ordinal and case-sensitive, without Unicode normalization. The result is independent of input order. Null and non-string elements throw InvalidCastException, even after the running result becomes empty.

Examples

{"running", "walking", "talking"} | fold(common-suffix) → "ing"
