Someone took a phrase made of words separated by single spaces, appended each word's position in the phrase (starting at 1) to its end, and then shuffled the words. The result is the string shuffled.
For instance, the phrase Keep it simple could have turned into simple3 Keep1 it2.
Restore the original phrase: the words in the right order, without the numbers, separated by single spaces.
Example 1
shuffled='world2 Hello1' → 'Hello world'
The word tagged 1 is "Hello" and the word tagged 2 is "world".
Example 2
shuffled='late3 never4 Better1 than2' → 'Better than late never'
Put the words in order of their tags 1, 2, 3, 4 and drop the digits.
Example 3
shuffled='Go1' → 'Go'
Constraints
