Sum of Squares of Digits

Given a non-negative integer \( n \), compute and print the sum of the squares of its digits. In other words, if \( n \) is represented in base 10 as \( d_kd_{k-1}\ldots d_0 \), you need to calculate:

\( \sum_{i=0}^{k} d_i^2 \)

The input consists of a single non-negative integer. The output should be the computed sum printed to standard output.
