 **Example 1:**
 
-**Input:** nums = [0,2,1,5,3,4]
+**Input:** nums = \[0,2,1,5,3,4]
 
-**Output:** [0,1,2,4,5,3]
+**Output:** \[0,1,2,4,5,3]
 
 **Explanation:** The array ans is built as follows: 
 
-ans = [nums[nums[0]], nums[nums[1]], nums[nums[2]], nums[nums[3]], nums[nums[4]], nums[nums[5]]] 
-    = [nums[0], nums[2], nums[1], nums[5], nums[3], nums[4]]    
-    = [0,1,2,4,5,3]
+ans = [nums[nums\[0]], nums[nums\[1]], nums[nums\[2]], nums[nums\[3]], nums[nums\[4]], nums[nums\[5]]] 
+    = [nums\[0], nums\[2], nums\[1], nums\[5], nums\[3], nums\[4]]
