Ruby Basic Exercises: Check three given integers and return true if two or more of them have the same rightmost digit


Write a Ruby program to check three given integers and return true if two or more of them have the same rightmost digit.

Ruby Code:

def check_num(a, b, c)
    x = a % 10
	y = b % 10
	z = c % 10
	if(x == y)
		return true
	end	
	if(x == z)
		return true
	end
	return (y == z)
end
print check_num(9, 12, 22),"\n"
print check_num(112, 202, 52),"\n"
print check_num(102, 203, 405)

Output:

true
true
false
