A file has multiple records each having three 30-bit long fields(field1,field2,field3).There is also a lookup file,LOOK_UP.dat.Now, we need to consider only the last ten digits of field1 and lookup the file LOOK_UP.dat. If there a match then field2 and field3 should replaced with corresponding data from the lookup file. otherwise that particular record,for which there is no match, should be stored in a seperate file.
