Write a function createCounter. It should accept an initial integer init. It should return an object with three functions.
The three functions are:
Examples
Example 1
Input: init = 5, calls = ["increment","reset","decrement"]
Output: [6,5,4]
Explanation:
const counter = createCounter(5);
counter.increment(); // 6
counter.reset(); // 5
counter.decrement(); // 4
Example 2
Input: init = 0, calls = ["increment","increment","decrement","reset","reset"]
Output: [1,2,1,0,0]
Explanation:
const counter = createCounter(0);
counter.increment(); // 1
counter.increment(); // 2
counter.decrement(); // 1
counter.reset(); // 0
counter.reset(); // 0
Constraints
-1000 <= init <= 10000 <= calls.length <= 1000calls[i] is one of "increment", "decrement" and "reset"
