What if there is more then one way to get the desired sum? Should it return '''all''' of the pairs or only '''a''' pair? Are we to assume the integers in the array are unique? --[[User:Thundergnat|Thundergnat]] ([[User talk:Thundergnat|talk]]) 22:21, 4 October 2016 (UTC)

E.g. when all numbers in the list are even,
and the desired sum is odd. -- [[User:Hajo|Hajo]] ([[User talk:Hajo|talk]]) 13:53, 5 October 2016 (UTC)
