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.
Solution

public:
int maxArea(vector<int>& height) {
int most = 0,i=0,j=height.size()-1;
while(i<j){
int h=min(height[i],height[j]);
most=max(most,h*(j-i));
while(height[i]<=h&&i<j) i++;
while(height[j]<=h&&i<j) j--;
}
return most;
}
