Challenge

Given two strings a and b, return the shortest string s so that s starts with a and ends with b.

(Inspired by https://chat.stackexchange.com/transcript/message/57816868#57816868 )

Examples

'ABCDEF', 'EFGHI' -> 'ABCDEFGHI'
'AAAAAA', 'AAAAAAAA' -> 'AAAAAAAA'
'ABC', '123' -> 'ABC123'
'', 'ABCDE' -> 'ABCDE'
'ABCD', 'ABCD' -> 'ABCD'
'', '' -> ''
