Python-Given a list of distinct integers from 0 to a value MAX_VALUE, write a function to produce a string that describes the ranges of numbers missing from the list. The items in the result should be sorted in ascending order and separated by commas. When a gap spans only one number, the item is the number itself; when a gap is longer, the item comprises the start and the end of the gap, joined with a minus sign.

empty array is not possible - (note first entry could be other than 0)

more than one missing element

MAX_VALUE will be given as input

example

MAX_VALUE = 1000 VALUES = [0, 1, 2, 50, 52, 75] RESULT = "3-49,51,53-74,76-1000"

Code must start with these two line !

def missingElementStepIII(arr,max_value):

return_value= "";

arr.sort()

#setup start start = arr[0] end = arr[0]

#check for missing elements for i in range(1,len(arr)): if (arr[i] - arr[i-1] > 1): end = arr[i-1] if (end == start): return_value+=str(start) else: return_value+=str(start) + "-" + str(end) start = arr[i] #handle last element in the array if (start != max_value): if (start == arr[-1]): return_value+=","+str(start) else: return_value+=","+str(start)+"-"+str(max_value) return return_value

I get this when I run the code
