Count Visitors

---

Implement the missing code, denoted by ellipses. You may not modify the pre-existing code.

You've launched your brand new web application not long ago, and while in beta it got beta satisfied visitors. Encouraged by such success, you decided to go ahead and push the very first stable version live.

You know that each beta visitor spent at least k minutes on your app, so now you'd like to keep track of new visitors of your web application that spent at least k minutes on it. Given the amount of time the visitors used your application and the value of k, return the total number of users that used your app for at least k minutes including those from beta.

Example

For beta = 22, k = 5, and visitors = [4, 6, 6, 5, 2, 2, 5],
the output should be
solution(beta, k, visitors) = 26.

4 new visitors spent at least 5 minutes on your application, which summed up with 22 satisfied beta users gives 26.

Input/Output

• [execution time limit] 4 seconds (py3)

• [input] integer beta

  The number of satisfied users of the beta version.

  Guaranteed constraints:
  1 ≤ beta ≤ 1000.

• [input] integer k

  The minimum amount of time each satisfied beta visitor spent on your application.

  Guaranteed constraints:
  1 ≤ k ≤ 100.

• [input] array.integer visitors

  An array of visitors, where visitors[i] is the number of minutes the i^th^ visitor spent on the app.

  Guaranteed constraints:
  0 ≤ visitors.length ≤ 100,
  1 ≤ visitors[i] ≤ 100.

• [output] integer

  The total number of visitors that spent at least k minutes on your app.

Solution

class Counter(object):
    
    def __init__(self, value) -> None:
        self.value = value

    def inc(self):
        self.value += 1

    def get(self):
        return self.value


def solution(beta, k, visitors):
    counter = Counter(beta)
    for visitor in visitors:
        if visitor >= k:
            counter.inc()
    return counter.get()
