题目:

1, 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.

思路:

左右向中间遍历,如果左边高度大于右边高度,则右边游标左移,因为此时只有左移才有机会大于当前最大面积。否则同理。

算法:

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