解题思路

双指针

 public int maxArea(int[] height){
      int maxArea = 0;
      int l = 0;
      int r = height.length - 1;
      while(l < r){
         maxArea = Math.max(maxArea,(r-l)*Math.min(height[r],height[l]));
         if(height[l] < height[r])
            l++;
         else
            r--;
      }
      return maxArea;
   }
