+In a array A of size 2N, there are N+1 unique elements, and exactly one of these elements is repeated N times.
+
+Return the element repeated N times.
+
+
+Example 1:
+
+Input: [1,2,3,3]
+Output: 3
+
+Example 2:
+
+Input: [2,1,2,5,3,2]
+Output: 2
+
+Example 3:
+
+Input: [5,1,5,2,5,3,5,4]
+Output: 5
+
+ 
+
+Note:
+
+    4 <= A.length <= 10000
+    0 <= A[i] < 10000
+    A.length is even
