Hi, I have two files : File A contains the following : ((((9,(6,8)),((4,((3,2),1)),5)),(12,11)),(13,(7,10)));
File B contains the follwoing: 1 A 2 B 3 C 4 D 5 E 6 F 7 G 8 H 9 I 10 J 11 K 12 L 13 M Based on the file B, I want to modify the file A such that all numerics in file A get changed to the alphabets in column 2 of file B (by mapping column 1 of file B to file A) such that file A is effectvly modified to : ((((I,(F,H)),((D,((C,B),A),E)),(L,K)),(M,(G,J))); Is there a way of doing it in perl ? Thanks
