Given a collection of intervals, merge all overlapping intervals.
For example,
Given [1,3],[2,6],[8,10],[15,18],
return [1,6],[8,10],[15,18].
思路:先对输入数据按start递增排序,然后再进行合并。
1 bool comp( Interval interval1, Interval interval2 ) { 2 return interval1.start < interval2.start; 3 } 4 5 class Solution { 6 public: 7 vector<Interval> merge( vector<Interval> &intervals ) { 8 sort( intervals.begin(), intervals.end(), comp ); 9 vector<Interval> ret; 10 for( auto iter = intervals.begin(); iter != intervals.end(); ++iter ) { 11 if( ret.empty() || ret.back().end < iter->start ) { 12 ret.push_back( *iter ); 13 } else { 14 ret.back().end = max( ret.back().end, iter->end ); 15 } 16 } 17 return ret; 18 } 19 };
