#Python program to find the length of an array

def find_len(arr):
  #Initialize the counter with 0
  count = 0

  #Run a for loop to go through all the elements of the array
  for element in arr:

    count = count + 1
    
  #Return the value of counter after exiting the for loop

#Function Call:
