alg_sum_powers_v1_1419126231_143
A robot walks along a number line from position 1 to 1999. At each point $x$, it checks whether $|2x - 1864| \le 1862$. For each such $x$, it adds $x^2$ to a total log. After finishing, it reports the sum modulo $3573$. What value does it report?

nt_count_digit_sum_v1_1520064083_9414
Let the target sum be the minimum value of $x + y$ over all pairs of positive integers $(x, y)$ such that $xy = 100$. Let $N$ be the number of positive integers $n$ such that $1 \leq n \leq 58081$ and the sum of the digits of $n$ equals the target sum. Compute the remainder when $44121 \cdot N$ is divided by $80875$.
