Given an integer n, return a counter function. This counter function initially returns n and then returns 1 more than the previous value every subsequent time it is called (n, n + 1, n + 2, etc).
Input: n = 10 ["call","call","call"]
Output: [10,11,12] Explanation: counter() = 10 // The first time counter() is called, it returns n. counter() = 11 // Returns 1 more than the previous time. counter() = 12 // Returns 1 more than the previous time.
Input: n = -2 ["call","call","call","call","call"]
Output: [-2,-1,0,1,2] Explanation: counter() initially returns -2. Then increases after each sebsequent call.
Given an integer n, return a counter function. This counter function initially returns n and then returns 1 more than the previous value every subsequent time it is called (n, n + 1, n + 2, etc).
