Yes, it is possible to get the accurate result from the given data.
The coordinates (i,j,k) where metallic balls are present can be determined by finding the set elements in both matrix1 and matrix2.
Additional data is not required as the given data is sufficient to determine the coordinates.
The coordinates can be obtained by iterating through the elements of matrix1 and matrix2 and checking for set elements.
