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).
+
Example 1:
+ +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. ++ +
Example 2:
+ +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. ++ +
+
Constraints:
+ +-1000 <= n <= 10000 <= calls.length <= 1000calls[i] === "call"
