If you have a way to tell "regular" values from discrepant ones, it's easy to
modify the program to account for that and print only the values of discrepant
columns. One way could be to look for the value that appears most times in a
row, and consider that value normal and all the others discrepant. But again,
you could have two values repeated the same number of times, so that would not
help. That's why it's important to have an unambiguous rule.
