<pre>the cat sat on the mat -> mat cat -> the mat sat on the cat

===Idiomatic===

The task description talks about items in lists, but the examples are space-delimited substrings of strings.

The handler here deals with items in lists and leaves it to the calling code to sort out the rest.

set output to output as text

set AppleScript's text item delimiters to astid

{{output}}

Data M: 'the cat sat on the mat' Order N: 'cat mat' --> 'the cat sat on the mat'

Data M: 'A B C A B C A B C' Order N: 'C A C A' --> 'C B A C B A A B C'

Data M: 'A B' Order N: 'B' --> 'A B'

Data M: 'A B' Order N: 'B A' --> 'B A'

Or with, say, lists instead of substrings:

set listOfLists2 to {{"aardvark", "duck-billed platypus", "banana"}, {1, 2, 3, 4, 5}}

This solution is a tad bit whimsical (and a testament to the flexibility of the language that it allows something like this). <code>make-slots</code> replaces elements from ''M'' with <code>_</code> from the <code>fry</code> vocabulary according to the elements in ''N''. For example,

produces <code>{ "the" _ "sat" "on" "the" _ }</code>. Then, <code>reorder</code> fries elements from ''N'' into the sequence. This is much like a regular fried quotation.

Finally, <code>input<sequence</code> is a smart combinator (a combinator that infers the stack effect of one or more of its inputs) that takes a sequence and a quotation and makes it so that from inside the quotation, you can think of sequence elements as though they were data stack objects. This is precisely what we want so that we can fry them.

Works in both languages. Assumes a single blank separates items:

This is a simple version that assumes that ''all'' items in the order list are present in the list to be arranged:

foreach item $theOrderList {incr n($item)}

set is {}

foreach item $theOrderList i $is {lset theList $i $item}

return $theList

This is a more sophisticated version that handles items in the order list not being present in the list to be arranged:

foreach item $theOrderList {incr n($item)}

set is -

}

return $theList

Demonstration code (produces the same output from both implementations):

"the cat sat on the mat" "mat cat"

"the cat sat on the mat" "cat mat"

A dictionary is used to hold count of the words in N, which is decremented as the words are used up.

A cycle of the words is consumed to track the replacement values.

It is assumed that there are no leading/trailing/consecutive spaces (easy to cover with a .filter()).
