    Calculate the total learning intensity score for a student's assignment by summing the squared difficulty levels of the even-numbered practice problems, given the total number of problems assigned. The difficulty level of each even-numbered problem corresponds to its position in the sequence, and only even-numbered problems are considered in the calculation.
