双指针解法。 需要理解最大面积

public class Solution
{
    //双指针解法，首先要理解
    public int MaxArea(int[] height)
    {
        int res = 0, size = height.Length;
        if (height.Length == 0) return res;
        int i = 0, j = size - 1;
        while (j > i)
        {
            int area = (j - i) * Math.Min(height[j], height[i]);
            if (area >= res)
            {
                res = area;
            }
            if (height[j] > height[i])
            {
                i++;
            }
            else
            {
                j--;
            }
        }

        return res;
    }
}
