+/*************************************************************************************** 
+ *
+ * Given two arrays, write a function to compute their intersection.
+ * 
+ * Example:
+ * Given nums1 = [1, 2, 2, 1], nums2 = [2, 2], return [2, 2].
+ * 
+ * Note:
+ * Each element in the result should appear as many times as it shows in both arrays.
+ * The result can be in any order.
+ * 
+ * Follow up:
+ * What if the given array is already sorted? How would you optimize your algorithm?
+ * What if nums1's size is small compared to num2's size? Which algorithm is better?
+ * What if elements of nums2 are stored on disk, and the memory is limited such that you
+ * cannot load all elements into the memory at once?
+ * 
+ ***************************************************************************************/

+ /* Solution
+  * --------
+  *
+  * Follow up:
+  * 
+  * 1)If the given array is already sorted we can skip the sorting.
+  * 
+  * 2)If nums1 is significantly smaller than nums2 we can only sort nums1 and then binary
+  * search every element of nums2 in nums1 with a total complexity of (MlogN) or if nums2
+  * is already sorted we can search every element of nums1 in nums2 in O(NlogM)
+  *
+  * 3)Just like 2), we can search for every element in nums2, thus having an online
+  * algorithm.
