+    it takes theta(n) to merge each level in recursion tree. 
     total height of the recursion is theta(lg(n))
-    merging start from the first level to lg(k)
+    merging start from the first level to lg(k):
         theta(n(lg(n) - lg(k))) = theta(n(lg(n/k)))
 Hence, it takes T(n) = theta(n(lg(n/k))) to merge the sublists.
