首先将区间按起点由小到大排序，这样相邻的两个就能通过终点判断是否重合。
|
|
|
|
|
|
|
|
```python
|
|
class Solution:
|
|
def merge(self, intervals):
|
|
if not intervals:
|
|
return []
|
|
intervals.sort()
|
|
merged = []
|
|
l = len(intervals)
|
|
m = intervals[0]
|
|
for x in range(l-1):
|
|
j = intervals[x+1]
|
|
if m[1] >= j[0]:
|
|
if m[1] <= j[1]:
|
|
m = [m[0], j[1]]
|
|
else:
|
|
continue
|
|
else:
|
|
merged.append(m)
|
|
m = j
|
|
if m:
|
|
merged.append(m)
|
|
return merged
|
|
```
