public class Solution { public int maxArea(List<Integer> height) { if(height == null || height.size() < 2) return 0; int max = 0, left = 0, right = height.size() - 1; while(left < right){ int curArea = Math.min(height.get(left), height.get(right)) * (right - left); max = Math.max(max, curArea); if(height.get(left) < height.get(right)) left++; else right--; } return max; } }
