CODE

#function to find largest rainfall

   large = 0
  
   #finding largest rainfall
   for i in range(1, n):
       if arr[i] > arr[large]:
           large = i
   #return index of largest rainfall
   return large

#function to find smallest rainfall

   small = 0
  
   #finding smallest rainfall
   for i in range(1, n):
       if arr[i] < arr[small]:
           small = i
   #return index of smallest rainfall
   return small
  
#function to find average rainfall

   total = 0
  
   #calculating total rainfall
   for i in range(n):
       total = total + arr[i]
   #calculating average rainfall
   avg = total / n
  
   #returns average
   return avg

#function to print classified table
