The answer for the first image is wrong. It should be 54784197.
If one looks at the answer set, he/she will see people having been bypassing the first test by fixing the answer. The test cases should be fixed to calculate the sum dynamically with some function forbidden to the user.
@goc3 please check if the test is incorrect as @Rafael mentions.
@Dyuman Joshi: the test suite and description have been updated with the value provided by Rafael S.T. Vieira. At some point in time the image was changed, as the early solutions did not require any hard coding.
