    3195 - Find the Minimum Area to Cover All Ones I\.

    Medium

    You are given a 2D binary array grid. Find a rectangle with horizontal and vertical sides with the smallest area, such that all the 1's in grid lie inside this rectangle.

    Return the minimum possible area of the rectangle.

    Example 1:

    Input: grid = \[\[0,1,0],1,0,1]

    Output: 6

    Explanation:

    The smallest rectangle has a height of 2 and a width of 3, so it has an area of 2 * 3 = 6.

    Example 2:

    Input: grid = \[\[1,0],0,0]

    Output: 1

    Explanation:

    The smallest rectangle has both height and width 1, so its area is 1 * 1 = 1.

    Constraints:

    • 1 <= grid.length, grid[i].length <= 1000

    • grid[i][j] is either 0 or 1.

    • The input is generated such that there is at least one 1 in grid.
