alg_telescope_v1_1218484723_3861
A robot moves along a number line, starting at 0. On step $k$ (for $k = 0$ to $1478$), it jumps forward by $(k+1)^2 - k^2$ units. After completing all jumps, it reports its total position modulo the number of distinct signal strengths $t$ in the range $[7, 9928]$ that can be generated using combinations of 3-unit and 4...
