ProgramGuruTo count the number of occurrences of a specified element in an array in Ruby, you can use methods like count, select, or a loop to iterate through the array and count each occurrence.
In this example,
numbers with values 10, 20, 30, 40, 30, 50.count method on the array to count occurrences of element 30.numbers = [10, 20, 30, 40, 30, 50]
puts "Number of occurrences of element 30: #{numbers.count(30)}"Number of occurrences of element 30: 2
In this example,
fruits with values 'apple', 'banana', 'cherry', 'banana'.select method on the array to select elements equal to 'banana'.size method on the selected array to get the count of occurrences of 'banana'.fruits = ['apple', 'banana', 'cherry', 'banana']
count = fruits.select { |fruit| fruit == 'banana' }.size
puts "Number of occurrences of element 'banana': #{count}"Number of occurrences of element 'banana': 2
