Problem Explanation

Explanation:

The problem asks us to find the number of users that have been reported at least N times consecutively.

We can solve this problem by iterating through the array of report counts and checking if the current count is greater than or equal to N and the previous count was also greater than or equal to N. If this condition is met, we increment a counter for the number of users meeting the criteria.

Algorithm:

  1. Initialize a counter variable consecutiveUsers to 0.
  2. Iterate through the array of report counts.
  3. Check if the current count is greater than or equal to N and the previous count was also greater than or equal to N.
  4. If the condition is met, increment consecutiveUsers.
  5. Return consecutiveUsers.

Time Complexity:

The time complexity of this solution is O(N), where N is the number of elements in the reportCounts array.

Space Complexity:

The space complexity of this solution is O(1) as we are using constant extra space.

Solution Code

class Solution {
    public int getConsecutiveUsers(int[] reportCounts, int N) {
        int consecutiveUsers = 0;
        for (int i = 1; i < reportCounts.length; i++) {
            if (reportCounts[i] >= N && reportCounts[i - 1] >= N) {
                consecutiveUsers++;
            }
        }
        return consecutiveUsers;
    }
}
