+</sup>
+
+## Description
+
+You are given a string containing a sequence of character sequences separated by commas.
+
+Write a function which returns a new string containing the same character sequences except the first and the last ones but this time separated by spaces.
+
+If the input string is empty or the removal of the first and last items would cause the resulting string to be empty, return an empty value (represented as a generic value NULL in the examples below).
+
+**Examples**
+
+```
+"1,2,3"      =>  "2"
+"1,2,3,4"    =>  "2 3"
+"1,2,3,4,5"  =>  "2 3 4"
+
+""     =>  NULL
+"1"    =>  NULL
+"1,2"  =>  NULL
+```
+
+## Solution
+
+```javascript
+const array = arr => {
+  const strArr = arr.split(',')
+
+  if (strArr.length <= 2) return null
+
+  return strArr.slice(1, strArr.length - 1).join(' ')
+}
+```
