Ruby Basic Exercises: Check three given integers x, y, z and return true if one of y or z is close while the other is far

Ruby Basic: Exercise-54 with Solution

Write a Ruby program to check three given integers x, y, z and return true if one of y or z is close (differing from a by at most 1), while the other is far, differing from both other values by 3 or more.

Ruby Code:

def check_num(x, y, z)
  if (y-z).abs < 3
        return false
    end
    return (x-y).abs<=1 && (x-z).abs>=3 || (x-z).abs<=1 && (x-y).abs>=3
end
print check_num(2, 3, 11),"\n"
print check_num(2, 3, 4),"\n"
print check_num(5, 2, 4)

Output:

true
false
false

Previous: Write a Ruby program to check three given integers and compute their sum. However, if one of the values is 17 then it does not count towards the sum and values to its right do not count.
Next: Write a Ruby program to check three given integers and return true if the three values are evenly spaced, so the difference between small and medium is the same as the difference between medium and large.
