Write a function createCounter. It should accept an initial integer init. It should return an object with three functions.
The three functions are:
+ +increment() increases the current value by 1 and then returns it.decrement() reduces the current value by 1 and then returns it.reset() sets the current value to init and then returns it.+
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"
