(2) to search from the sorted file in step(1) and find all the buildings, which start with "D" and the coordinates shown in the map are in the range of B5 to B7 (including B5, B6 and B7), and print them (with line numbers from the input file) to an output file, named Lab2output.txt. (3) to search from the sorted file in step(1) and find all the buildings which contain "ter" as part of the building name (Ignore case distinctions) and the coordinates shown in the map are either C6 to C7, or D6 to D7, and print (append) them (with line numbers from the input file), at the end of the same output file, named Lab2output.txt The following is the sample output of Lab2output.txt: 129 David P.
