I need help solving this problem.

Question

Develop a method that will transfer data from an one-dimensional array to a

three dimensional array in the reverse order as show below:

public void reverseTransfer(int[ ] a, int[ ][ ] b){

// complete this method.

}

Answer 1

class ArrayXfer

{

public int [][] Create2D(int N)

{

int A[][] = new int[N/2+1][N/2+1];

return(A);

}

public int [][][] Created3D(int N)

{

int A[][][] = new int [N/3+1][N/3+1][N/3+1];

return(A);

}

public void ReverseTransfer ( int [] a, int [][] b)

{

int iIndexPos = a.length-1;

int N=b[0].length;

for (int iLoop=0; iLoop<2; iLoop++)

{

for (int jLoop=0; jLoop<N; jLoop++)

{

b[iLoop][jLoop] = a[iIndexPos--];

if (iIndexPos<0) { break; }

}

}

}

public static void main (String args[])

{

int N=20;

int A[] = new int[N];

for (int iLoop=0; iLoop<N; iLoop++) { A[iLoop]=iLoop+1; }

ArrayXfer arrayXfer = new ArrayXfer();

int B[][]= arrayXfer.Create2D(N);

arrayXfer.ReverseTransfer(A,B);

for (int iLoop=0; iLoop<2; iLoop++)

{

for (int jLoop=0; jLoop<B[0].length; jLoop++)

{

System.out.print(B[iLoop][jLoop]+" ");

}

System.out.println("\n");

}

}

}
