# 57. Insert Interval

###### Link : https://leetcode.com/problems/insert-interval/description/

## 題目
插入一個範圍，並把重疊的範圍合併
## 程式碼

class Solution {
public:
    vector<vector<int>> insert(vector<vector<int>>& intervals, vector<int>& newInterval) {
        int locate = intervals.size();
        for(int i = 0;i < intervals.size();i++){
            if(intervals[i][0] > newInterval[0]){
                locate = i;
                break;
            }
        }
        intervals.insert(intervals.begin() + locate, newInterval);//將newInterval和intervals按照順序合併
        for(int i = 0;i < intervals.size()-1;i++){
            while(i+1 < intervals.size() && intervals[i][1] >= intervals[i+1][0]){//如果有重疊
                intervals[i][1] = (intervals[i+1][1] > intervals[i][1])?intervals[i+1][1]:intervals[i][1];//將比較大的下界設為前者的下界
                intervals.erase(begin(intervals)+i+1);//刪除後者
            }
        }
        return intervals;
    }
};
