this is my text file:
textfile line1: 1 => A B C D E F G
textfile line2: 2 => B F G
textfile line3: 3 => D E F
textfile line4: 4 => A C
textfile line5: 5 => A D E F G
textfile line6: 6 => G

1 => A B C D E F G
5 => A D E F G #(Since, there are 5 matches in the above array..and the order decreases depending pon the matches)
2 => B F G
3 => D E F
4 => A C
6 => G
