Ruby Basic Exercises: Check two given integers, each in the range 10..99, return true if there is a digit that appears in both numbers

Ruby Basic: Exercise-51 with Solution

Write a Ruby program to check two given integers, each in the range 10..99, return true if there is a digit that appears in both numbers.

Ruby Code:

def check_num(a, b)
    a_digit = a%10
	b_digit = b%10;
	a /= 10;
	b /= 10;
	return (a == b || a == b_digit || a_digit == b || a_digit == b_digit)
end
print check_num(9, 12),"\n"
print check_num(15, 51),"\n"
print check_num(12, 23)

Output:

false
true
true

Previous: Write a Ruby program to check two given integers and return the larger value. However if the two values have the same remainder when divided by 5 then return the smaller value and if the two values are the same, return 0.
Next: Write a Ruby program to check three given integers and return their sum. However, If one of the values is the same as another of the values, it does not count towards the sum.
