题目:
分析:
1、双指针,储水为(R-L )* 二者较小高度,如题目,(9-2)* 7 = 49
2、双指针向中间靠,每次移动较矮的指针。
代码:
java
public int maxArea(int[] height) {
int left = 0;
int right = height.length - 1;
int max = 0;
while (left < right) {
if (height[right] > height[left]) {
max = Math.max(max, (right - left) * height[left]);
left++;
} else {
max = Math.max(max, (right - left) * height[right]);
right--;
}
}
return max;
}
