I want to create some function in java (phseudo code will also help) that does the following.

I have a 2d array of Objects called vertices. Each vertice has a value of 0,1 or 2

the number of arrays of vertecies are (arrays containing 3 vertices) are determined by n = Math.pow(3,n-2) where n ranges from 1 to 10;

some n value is passed as a parameter and then i want to create a labeling function or class to do the following.

the label lentgh is equal to n-1

so if n =4 then the label should be 3 letters long.

Also the specified vertex in the array is given as a parameter so you know the place in the array where the specified vertex lies.

for example:

this is my constructor:

public PrecedenceGraph(int N)

{

/*

The constructor creates the precedence graph TN,

where N is passed as a parameter.\

*/

n = N;

tokens = new Queue(N);

maxnumberoftokens = N;

int numbox = 0;

if(n>1){

labellentgh = n-2;

}

if (N == 1){

Vertex v0 = new Vertex(0);

vertexarray = new Vertex[1][1];

vertexarray[0][0] = v0;

}

else if (N == 2){

numbox = (int) Math.pow(3,N-2);

vertexarray = new Vertex[3][numbox];

Vertex v0,v1,v2;

v0 = new Vertex(0);

v1 = new Vertex(1);

v2 = new Vertex(2);

vertexarray[0][0] = v0;

vertexarray[1][0] = v1;

vertexarray[2][0] = v2;

}

else if(N>2){

numbox = (int) Math.pow(3,N-2);

vertexarray = new Vertex[3][numbox];

for (int i = 0 ; i < numbox;i++){

for (int j = 0 ; j < 3; j++){

vertexarray[j][i] = new Vertex(j);

}

}

}

}

for example.

if n = 3 an array is created

[[0,1,2]]

if n = 4

[[0,1,2],[0,1,2]...... up until there is 9 arrays of [0,1,2]]

so if i want to genereate a label for n = 4 and the element surrounded in the brackets is :

[[0,1,2],[0,(1),2], [0,1,2]]

the label must be 11

also

n = 4

[[0,1,2],[0,1,2].,[0,1,2],[0,(1),2]..... up until there is 9 arrays of [0,1,2]]

101

every 3 arrays counts as a 0 1 or 2 for the first part.
