Question Definition
Given n non-negative integers a1, a2, …, an, where each represents a point at coordinate (i, ai). n vertical lines are drawn such that the two endpoints of line i is at (i, ai) and (i, 0). Find two lines, which together with x-axis forms a container, such that the container contains the most water.
Note: You may not slant the container and n is at least 2.
Java Solution
public int maxArea(int[] height) {
if(height.length < 2) return 0;
int max = Math.min(height[0], height[height.length - 1]) * (height.length - 1);
int left = 0;
int right = height.length - 1;
while(left < right){
max = Math.max(max, Math.min(height[left], height[right]) * (right - left));
if (height[left] < height[right]) ++left;
else --right;
}
return max;
}
