## [algorithm experience] array 11, 15

11. Container with the most water
Give you n nonnegative integers a1, a2,..., an, each representing a point (i, ai) in the coordinate. Draw n vertical lines in the coordinates. The two endpoints of vertical line i are (i, ai) and (i, 0). Find two of these lines so that the container they form with the x-axis can hold the most water.
My idea: ...
