It means that a O(n2) solution can solve it. We simply need to simulate the robot's moves. I hope that this can help you figure out the solution of some problems quicker :) Note: The above method may not always work in all problems. Some may require algorithms that have complex ...

每次询问给出 l,r,x,你需要回答 a_i \not = x,i\in [l,r],i 的值。 求出任意一个即可。 简要分析 pos_i 表示对于第 i 个数满足 a_j = a_i ,j \in [l,i] 的最小 l。 对于每次询问,判断 a_r 与x 的关系,如果两者不想等就判断 pos_r > l 即可。 代码实现 void solve() { ccin...
