--------------

In such problems, calculations is not a major goal.

The major goal is to correctly organize calculations by choosing correctly the base for comparison.


This problem asks to compute the percent error in the player's guess.

It means that the base is the player's guess value.


Had the problem asked about the percent of the deviation from the actual score, the base for comparison would be actual score.
