题意为给你若干个圆,每个圆的颜色对应一个频率,如果两个圆有公共部分,那么这两个圆之间可以走,你可以从起点开始,从频率小的圆走向频率大的圆并且到达终点后,从频率大的圆走向频率小的圆,最终回到起点,路径中每个圆只能走一次,是否存在一个满足条件的方案. 这样的,把红点当做起点,把紫点当做终点,如果两个圆相交,那么从频率小的圆连接一条边指向频率大的圆,边容量为1.如此一来,相当于求起点到终点的最大流量是否不小于2即可.因为只要不小于2,说明有两条不相交的路径达到终点,只要把其中的一条路径反向即可. 由于…

炎炎夏日,还是呆在空调房里切切题吧. Container With Most Water,题意其实有点噱头,简化下就是,给一个数组,恩,就叫 height 吧,从中任选两项 i 和 j(i <= j),使得 Math.min(height[i], height[j]) * (j - i) 最大化,求解这个最大值. O(n^2) O(n^2) 复杂度的解法非常容易想到,直接两两枚举. var maxArea = function(height) { var len = height.length;…
