Leetcode Insert Interval

Given a set of non-overlapping intervals, insert a new interval into the intervals (merge if necessary).

You may assume that the intervals were initially sorted according to their start times.

Example 1:
Given intervals [1,3],[6,9], insert and merge [2,5] in as[1,5],[6,9].

Example 2:
Given [1,2],[3,5],[6,7],[8,10],[12,16], insert and merge [4,9] in as[1,2],[3,10],[12,16].

This is because the new interval [4,9] overlaps with[3,5],[6,7],[8,10].

代码如下：

/** * Definition for an interval. * struct Interval { *     int start; *     int end; *     Interval() : start(0), end(0) {} *     Interval(int s, int e) : start(s), end(e) {} * }; */class Solution {public:    vector<Interval> insert(vector<Interval>& intervals, Interval newInterval) {        vector<Interval> result;        int i;        for( i=0;i<intervals.size();i++)        {            if(newInterval.start > intervals[i].end)                result.push_back(intervals[i]);            else if(newInterval.end < intervals[i].start)            {                break;            }            else            {                newInterval.start = min(intervals[i].start,newInterval.start);                newInterval.end = max(intervals[i].end,newInterval.end);            }        }        result.push_back(newInterval);        for(;i < intervals.size();i++)            result.push_back(intervals[i]);        return result;    }};
