Sum of Squares

You are given a comma-separated list of integers as input. Your task is to compute the sum of the squares of these numbers.

For example, if the input is "1,2,3", then the output should be 1² + 2² + 3² = 14.

The input will be provided as a single line from stdin and your answer should be printed to stdout.

Note: Negative numbers should be squared as well (i.e. (-3)² = 9).
