    3311 - Construct 2D Grid Matching Graph Layout\.

    Hard

    You are given a 2D integer array edges representing an undirected graph having n nodes, where <code>edgesi = u<sub>i</sub>, v<sub>i</sub></code> denotes an edge between nodes <code>u<sub>i</sub></code> and <code>v<sub>i</sub></code>.

    Construct a 2D grid that satisfies these conditions:

    • The grid contains all nodes from 0 to n - 1 in its cells, with each node appearing exactly once.

    • Two nodes should be in adjacent grid cells ( horizontally or vertically ) if and only if there is an edge between them in edges.

    It is guaranteed that edges can form a 2D grid that satisfies the conditions.

    Return a 2D integer array satisfying the conditions above. If there are multiple solutions, return any of them.

    Example 1:

    Input: n = 4, edges = \[\[0,1],0,2,1,3,2,3]

    Output: [3,1,2,0]

    Explanation:

    Example 2:

    Input: n = 5, edges = \[\[0,1],1,3,2,3,2,4]

    Output: [4,2,3,1,0]

    Explanation:

    Example 3:

    Input: n = 9, edges = \[\[0,1],0,4,0,5,1,7,2,3,2,4,2,5,3,6,4,6,4,7,6,8,7,8]

    Output: [8,6,3,7,4,2,1,0,5]

    Explanation:

    Constraints:

    • <code>2 <= n <= 5 * 10<sup>4</sup></code>

    • <code>1 <= edges.length <= 10<sup>5</sup></code>

    • <code>edgesi = u<sub>i</sub>, v<sub>i</sub></code>

    • <code>0 <= u<sub>i</sub>< v<sub>i</sub>< n</code>

    • All the edges are distinct.

    • The input is generated such that edges can form a 2D grid that satisfies the conditions.
