Given a sorted integer array without duplicates, return the summary of its ranges.
For example, given [0,1,2,4,5,7], return ["0->2","4->5","7"].

Special thanks to @jianchao.li.fighter for adding this problem and creating all test cases.
代码如下：
public class Solution {
public List<String> summaryRanges(int[] nums) {
List<String>list=new ArrayList<String>();
int len=nums.length;
if(len==0) return list;
int begin=nums[0];
int end=nums[0];
for(int i=0;i<len;i++){
begin=nums[i];
while(i+1<len && nums[i+1]-nums[i]==1)
i++;
end=nums[i];
String s=null;
if(begin!=end)
s=""+begin+"->"+end;
else
s=""+begin;
list.add(s);
}
return list;
}
}
运行结果：
