Ruby Array Exercises: Compute the average values of a given array of except the largest and smallest values
Ruby Array: Exercise-31 with Solution
Write a Ruby program to compute the average values of a given array, except the largest and smallest values. The array length must be 3 or more.
Ruby Code:
def check_array(nums)
min = nums[0]
max = nums[0]
sum = 0
nums.each do |item|
sum = sum + item
if(item > max)
max = item
elsif(item < min)
min = item
end
end
return (sum-max-min).to_f/(nums.length - 2)
end
print check_array([3, 4, 5, 6]),"\n"
print check_array([12, 3, 7, 6]),"\n"
print check_array([2, 15, 7, 2]),"\n"
print check_array([2, 15, 7])
Output:
4.5 6.5 4.5 7.0
