 ## Description
+Given three integer arrays `nums1`, `nums2`, `nums3`, return a **distinct** array containing all the values that are present in **at least two** out of the three arrays. You may return the values in `any` order.
 
 **Example 1:**
 
 ```
-Input: a = "11", b = "1"
-Output: "100"
+Input: nums1 = [1,1,3,2], nums2 = [2,3], nums3 = [3]
+Output: [3,2]
+Explanation: The values that are present in at least two arrays are:
+- 3, in all three arrays.
+- 2, in nums1 and nums2.
 ```

-Two Out of Three
-```go
+```
+Input: nums1 = [3,1], nums2 = [2,3], nums3 = [1,2]
+Output: [2,3,1]
+Explanation: The values that are present in at least two arrays are:
+- 2, in nums2 and nums3.
+- 3, in nums1 and nums2.
+- 1, in nums1 and nums3.
 ```
 
+**Example 3:**
+
+```
+Input: nums1 = [1,2,2], nums2 = [4,3,3], nums3 = [5]
+Output: []
+Explanation: No value is present in at least two arrays.
+```
