D. On AtCoder Conference Problem Statement There is a circular pond with circumference (M). A hut and (N) people are located around the pond. For a real number (x) ((0\leq x < M)), the point (x) is defined as the position clockwise at distance (x) from the hut. The (i)-th person is at point (A_i)...

Consider an infinite linear axis where every integer coordinate holds an initial value of zero. The task involves processing $n$ point increment operations followed by anwsering $m$ range sum queries. Given that coordinates may span $[-10^9, 10^9]$ while $n, m \leq 10^5$, direct array allocation is...
