Given a non-negative int n, return the count of the occurrences of 7 as a digit, so for example 717 yields 2. (no loops). Note that mod (%) by 10 yields the rightmost digit (126 % 10 is 6), while divide () by 10 removes the rightmost digit (126/10 is 12). Your Answer: 1 public int count7(int n) 2{ 31 4} 15 Check my answer! Reset Next exercise Feedback
