Arrange a list of non-negative integers so their decimal strings form the largest possible number.
Return the result as a string. If every value is zero, return a single zero.
Inputnums = [10, 2]
Output"210"
Inputnums = [3, 30, 34, 5, 9]
Output"9534330"
1 ≤ nums.length ≤ 1000 ≤ nums[i] ≤ 1,000,000,000
