Question

I am trying to flatten a two dimensional array into a one dimensional array. This is what I currently have. I would like the flatten out my array so that the one dimensional array looks like this

   int[] oneDim = {1, 2, 3, 4, 5, 6, 7, 8 ,9 ,10, 11, 12};

This is what I currently have. I dont really know how to go about doing this. All help and input is appreciated.

   void setup() {
   int[][] twoDim = { {1, 2, 3, 4},
                      {5, 6, 7, 8},
                      {9, 10, 11, 12} }; 

   int[] oneDim = new int[twoDim.length];
   for (int i = 0; i < twoDim.length; i++) {
      for (int j = 0; j < twoDim[i].length; j++) {
        oneDim[j] += twoDim[j][i];
      }                  
    }
   println(oneDim);
  }

int[][] twoDim = { {1, 2, 3, 4},
                   {5, 6, 7, 8},
                   {9, 10, 11, 12} }; 
int x = twoDim.length;
int y = twoDim[0].length;
int[] oneDim = new int[x*y];
for (int i = 0; i < x; i++) {
  for (int j = 0; j < y; j++) {
    oneDim[i*y + j] = twoDim[i][j];
  }
}
println(oneDim);
