title: Change array in the TextView
body: <p>I've got an array:</p>
  
  <pre><code>int[][] a = new int [50][50];
  </code></pre>
  
  <p>Then, i'm write it into TextView ( variable: table)</p>
  
  <pre><code>StringBuilder strBuild = new StringBuilder();
  for(int ii = 0; ii &lt;= pow(2,n); ii++){//strings of the truth table
      for(int jj = 1; jj &lt;= pow(2,n); jj++){//rows...
          strBuild.append(a[ii][jj]);
          strBuild.append(" ");
      }
      strBuild.append("\n");
  }
  
  table.setText(strBuild.toString());
  </code></pre>
  
  <p>i've got next array (n=2 and defines dynamically)</p>
  
  <pre><code>0 0 1 0
  0 0 0 0
  0 1 1 1
  1 0 1 1
  1 1 0 0
  </code></pre>
  
  <p>But i want to get an array 2^n, 4x4 here, but if i will do</p>
  
  <pre><code>for(int jj = 1; jj &lt;= pow(2,n); jj++){
  </code></pre>
  
  <p>instead of</p>
  
  <pre><code>for(int jj = 0; jj &lt;= pow(2,n); jj++){
  </code></pre>
  
  <p>i will lose the third element in the first row. </p>
  
  <p>How i can move this value down to obtain next array?</p>
  
  <pre><code>0 0 1 0
  0 1 0 1
  1 0 1 1
  1 1 1 0
  </code></pre>
