Last update on June 06 2025 12:48:16 (UTC/GMT +8 hours)

Write a Ruby program to check whether it contains no 3 or it contains no 5.

Ruby Code:

def check_array(nums)
   noThree = true, noFive = true;
   i = 0;
   while i < nums.length && (noThree || noFive)
        if(nums[i] == 3)
			noThree = false
		elsif(nums[i] == 5)
			noFive = false
		end	
	i = i + 1
   end
   return (noThree || noFive)
end
print check_array([3, 7, 3, 3]),"\n"
print check_array([2, 8, 2, 9]),"\n"
print check_array([3, 8, 5, 9]),"\n"

Output:

true
[true, true]
false
