预处理:
由于数据大要用离散化.本题是离散化的经典教材.
算法:
(1)
枚举每个离散化后的行(或列),把相应行(或列)可以看成是区间的覆盖颜色.
注意覆盖顺序,应该上面的先处理,否则一个线段会重复被盖多次,算法退化.
使用线段树,复杂度 O(N^2logN)
usaco可以ac,但是ural上tle.
本题也是线段树的经典教材.

the algorithm in "ex.dpr" and algorithm "ex2.dpr" is identic ,i.e. time complexities are both O(N).
The memory complexity of "ex.dpr" is O(N), but that of "ex2.dpr" is O(1).
D[i] in "ex.dpr" is the

1.从最小的度的子节点搜 ac in 0.078s
2.大部分的规模直接以最小的度的子节点决策，剩下的由dfs调整
