Ruby Array Exercises: Check whether a given value appears everywhere in a given array

Last update on December 21 2024 10:17:03 (UTC/GMT +8 hours)

Write a Ruby program to check whether a given value appears everywhere in an given array. A value is "everywhere" in an array if it presents for every pair of adjacent elements in the array.

Ruby Code:

def check_array(nums)
   i = 0;
   val = 3
   while i < nums.length
       if(nums[i] != val && nums[i+1] != val)
			return false
		end	
	i = i + 1
   end
   return true
end
print check_array([3, 7, 3, 3]),"\n"
print check_array([2, 8, 2, 9]),"\n"
print check_array([3, 8, 5, 4, 3, 7]),"\n"

Output:

true
false
false
