title: print a table of decremented numbers
body: <p>I want to write a code that print a table like this:</p>
  
  <pre><code>5 5 5 5 5 5 5 5 5 
  5 4 4 4 4 4 4 4 5 
  5 4 3 3 3 3 3 4 5 
  5 4 3 2 2 2 3 4 5 
  5 4 3 2 1 2 3 4 5 
  5 4 3 2 2 2 3 4 5 
  5 4 3 3 3 3 3 4 5 
  5 4 4 4 4 4 4 4 5 
  5 5 5 5 5 5 5 5 5
  </code></pre>
  
  <p>I wrote a code to print a table as said above, but it just print 5's.
  I know that I have to use a condition to print such a table. What's the condition to print it ? </p>
  
  <pre><code>int main () {
  int  number = 5;
  
  for (int i = 0; i &lt; 9; i++) {
      for (int j = 0; j &lt; 9; j++) {
          if (condition)
              ...
          else
              cout &lt;&lt; number &lt;&lt; " ";
      }
      cout &lt;&lt; endl;
  }
  return 0;
  }
  </code></pre>
