This article provides a Python solution to find the middle element in a given integer array. The algorithm efficiently calculates the middle element for arrays with odd lengths or returns the average of the two middle elements for arrays with even lengths. By implementing this Python code, you can easily determine the middle element of any integer array.

def middle_element(lst):
  lst_len = int(len(lst))
  if len(lst) % 2 != 0:
return lst[lst_len // 2]
  else:
return ( lst[int(lst_len/2)-1] +
lst[int(lst_len/2)] ) / 2

Example usage:

array = [1, 9, 3, 4, 5,6,7,8,10]
middle_element = middle_element(array)
print("Middle Element:", middle_element)

#Output

 
Middle Element: 5
