A segment of an array is defined as a collection of consecutive elements in that array. The length of a segment is the number of elements in the segment. A repeating segment is a segment with all the elements in it having the same value. The following method returns the length of the longest repeating segment in a given int array. Complete the implementation of the method.

Answer The python program defines a function called is_dual that accepts an array parameter and check if the array is dual. If it meets the condition, the function returns true but returns false when the array is not dual.        Explanation:     def is_dual( array):

  if len(array) % 2 == 0:

      count = 0

      for i in range(0, len(array)//2, 2):

          if array[i] + array[i+1] == array[0] + array[1]:

              count += 1

      if count == len(array)//2:

          return True

      else:

          return False
