Indeed. There can never be a three character sequence in your string which occurs more frequently than a two character sequence. (Because the three character sequence contains two two character sequences.) `perl -E'sub Monkey::do{say$_,for@_,do{($monkey=[caller(0)]->[3])=~s{::}{ }and$monkey}}"Monkey say"->Monkey::do'`	[reply]

But what should be returned if we have string 'abcabcabcdef' with same amount of three-chars-long and two-chars-long string? 'ab' or 'abc'? I assume OP wants the longer one.	[reply]
