Reverse the data order

Suppose, I have a file (file.txt) that contain few numbers with characters.

1 2 3 4 (23)

23 2 1 (51)

2 1 4 (11)

And, I would like to read it in reverse order as given below. 

(23) 4 3 2 1

(51) 1 2 23

(11) 4 1 2

I tried: 

awk '{print $NF,$0}' file.txt | sort -nr

Is there a command-line in Linux or a mini-code (in AWK or in C++ or some other language) to perform this task?

awk '{for (i=NF;i>0;i--){printf $i" "};printf "\n"}' file.txt

Output:

(23) 4 3 2 1 

(51) 1 2 23 

(11) 4 1 2
