Problem 2: Remove a data point of raw_data from con_data

       Description: Arbitrarily choose a row of raw_data, call it data_point. We want to readjust con_data so that it contains exactly what it would contain if data_point had not been in file1A.dat (or file1B.dat if you must) in the first place.

Problem: Write a Matlab function, call it prob2, that takes as input a row (data_point) from raw_data and the matrix con_data and returns a modified con_data whose elements have values they would have had if the data point corresponding to data_point had not been in file1A.dat (or file1B.dat) in the first place.

Sample Output: If invoked as follows:

        con_data = prob2(raw_data(1,:),con_data)
where con_data is:
            1   0   1   0   1
            0   1   0   1   1
            1   0   1   1   1
            0   1   1   1   1
            1   1   1   1   1
the output should be
        con_data =

            1   0   0   0   1
            0   1   0   1   1
            0   0   1   1   1
            0   1   1   1   1
            1   1   1   1   1
