Need help writing a java program that back tracks the placement of n number of queens on a board where there placement prevents them from attacking each other. The in put from the scanner is a 2D Array containing 0 and 1 s. If it is a zero the square is empty no queen is on the square. If the square has a 1 then is occupied by a queen. The program should print true if non of the queens are occuping the same row, column and diagonal. Else false. I have attached funder details on the attached picture. Thank you

You are given an undirected graph.
Calculate the minimum spanning tree.
You will ouput only the total sum of all edges.
All vertices are accessible from all other vertices in the graph. There are no isolated
vertices.
Input Format
First line is number of vertices: v
Second line is number of (undirected) edges: e
The next e lines contain the 3 values: the two endpoints and the cost value of the edge
that joins them.
Constraints
The number of vertices will be less than 16
edge cost values will be less than 100
Output Format
Output a single integer, the sum of all edges that make up the minimum spanning tree.
Sample Input 0
4
6
0 19
0 29
0 3 10
1 2 2
1 3 10
239
Sample Output 0
20
Explanation 0
The graph contains 4 vertices and 6 undirected edges.
The sum of the edges in the MST is 20:
v1v2: 9
v2 - v3: 2
v3 v4: 9
9 +2+ 9 = 20
