QuestionYou are given asorted uniqueinteger arraynums.Arange[a,b]is the set of all integers fromatob(inclusive).Returnthesmallest sortedlist of ranges thatcover all the numbers in the array exactly**. That is, each element ofnumsis covered by exactly one of the ranges, and there is no integerxsuch thatxis in one of the ranges but not innums.Each range[a,b]in the list should be output as:"a->b"ifa != b"a"ifa == bExample 1:Input: nums = [0,1,2,4,5,7]
Output: ["0->2","4->5","7"]
Explanation: The ranges are:
[0,2] --> "0->2"
[4,5] --> "4->5"
[7,7] --> "7"Example 2:Input: nums = [0,2,3,4,6,8,9]
Out
