Stamp Collector

**Description:** A strip of n positions starts at 0. Apply q updates: add v to every position in [l, r]. Print the final value of every position. **Input:** Line 1: n q (1 <= n, q <= 2*10^5). Next q lines: l r v (1 <= l <= r <= n, -10^9 <= v <= 10^9). **Output:** n integers — the final values, space-separated. **Example:** 5 2 / 2 4 5 / 1 3 -2 -> -2 3 3 5 0.
