spli("") is default of split() without anything

if array's length smaller or equal to 1, It would return res=0.Otherwise test cases will be looking for another statement.If you don't insert any of them,It would return None

can sb explain that how does it work??

thanks <3

range(1,len(arr) is to loop through array, starting from index 1 to the last index of array. why do you do this? because you need to check the condition from second index which is index 1 for example: arr[1] - arr[1-1] > 1: imagine if you start from index 0 if it will be like this arr[0] - arr[0-1] or arr[0] - arr[-1]

Are you sure?

Not efficient, but he use primitive types, not wrapper class. Is valid solution.
