Write a method that returns how many times the value of 7 appears in an array of integers. For example, count7s({6, 77, 777, 3, 7, 5}) returns a 1 since the value 7 only appeared once in that array. Please note that you are NOT counting the number of times the DIGIT 7 appears in the array. count7s([3, 5, 7, 7, 2, -7, 6, 12, 9, 7]) → 3 count7s([7, 7, 7, 7, 7, 7, 7, 7, 7, 7, 7, 7, 7, 7]) → 14 count7s([6, -7, -7, 8, 154, 3, 0]) → 0 ...Save, Compile, Run (ctrl-enter) |
