In the second sample you can also fell 4-th tree to the right, after that it will occupy segment [10;19]. 题目大意: 无限长的数轴上有n个点,每个点的坐标为x[i],种有高度为h[i]的树,现在要把一些树砍到,被砍倒的树要么倒向左边,要么倒向右边,会分别把[xi - hi, xi] 和 [xi,...
Formally, a teleport located at pointxwith limitycan move Pig from pointxto any point within the segment[x; y], including the bounds. Determine if Pig can visit the friend using teleports only, or he should use his car. Input
