title: For loop incremented by variable, time complexity
body: <pre><code>for (int i = 1; i &lt; a; i++){
      for(int j = 1; j &lt; b; j = j + a){
          Function() &lt;-- O(1)
      }
  }
  </code></pre>
  
  <p>In this case, the outer loop will be executed 'a'times(O(a)), and
      the inner loop will be executed 'b/a' times(O(b/a)).</p>
  
  <p>Then the total time complexity will be O(a * b/a ) = O(b)?</p>
  
  <p>I am not this interpretation is right or not..</p>
