You are given a 2D binary array grid. You need to find 3 non-overlapping rectangles having non-zero areas with horizontal and vertical sides such that all the 1's in grid lie inside these rectangles.
Return the minimum possible sum of the area of these rectangles.
\n\nNote that the rectangles are allowed to touch.
\n\n\n
Example 1:
\n\nInput: grid = [[1,0,1],[1,1,1]]
\n\nOutput: 5
\n\nExplanation:
\n\n![\"\"](\"https://assets.leetcode.com/uploads/2024/05/14/example0rect21.png\")
(0, 0) and (1, 0) are covered by a rectangle of area 2.(0, 2) and (1, 2) are covered by a rectangle of area 2.(1, 1) is covered by a rectangle of area 1.Example 2:
\n\nInput: grid = [[1,0,1,0],[0,1,0,1]]
\n\nOutput: 5
\n\nExplanation:
\n\n![\"\"](\"https://assets.leetcode.com/uploads/2024/05/14/example1rect2.png\")
(0, 0) and (0, 2) are covered by a rectangle of area 3.(1, 1) is covered by a rectangle of area 1.(1, 3) is covered by a rectangle of area 1.\n
Constraints:
\n\n1 <= grid.length, grid[i].length <= 30grid[i][j] is either 0 or 1.grid.Compiled with clang 17 using the latest C++ 20 standard, and libstdc++ provided by GCC 11.
