Write a Ruby program to check whether the number of 2's is greater than the number of 5's of a given array of integers.

Ruby Code:

def check_array(nums)
   ctr = 0
   i = 0
   while i < nums.length
        if (nums[i] == 2)
			ctr = ctr + 1
		elsif (nums[i] == 5)
			ctr= ctr - 1
		end
       i += 1
   end
   return (ctr > 0)
end
print check_array([3, 5, 3, 3]),"\n"
print check_array([2, 3, 2, 5]),"\n"
print check_array([2, 2, 5, 5]),"\n"

Output:

false
true
false
