 ## Description
+Given an integer `num`, find the closest two integers in absolute difference whose product equals `num + 1` or `num + 2`.
+
+Return the two integers in any order.
 
 **Example 1:**
 
 ```
-Input: a = "11", b = "1"
-Output: "100"
+Input: num = 8
+Output: [3,3]
+Explanation: For num + 1 = 9, the closest divisors are 3 & 3, for num + 2 = 10, the closest divisors are 2 & 5, hence 3 & 3 is chosen.
 ```
