#+ANKI_DECK: study_deck_02 * TODO 0057. Insert Interval :medium: :PROPERTIES: :NEETCODE: [[file:../../roadmap.org::*0057. Insert Interval][0057. Insert Interval]] :END: You are given an array of non-overlapping intervals ~intervals~ where ~intervals[i] = [start_{i}, end_{i}]~ represent the start and the end of the ~i^{th}~ interval and ~intervals~ is sorted in ascending order by ~start_{i}~. You are also given an interval ~newInterval = [start, end]~ that represents the start and end of another interval. Insert ~newInterval~ into ~intervals~ such that ~intervals~ is still sorted in ascending order by ~start_{i}~ and ~intervals~ still does not have any overlapping intervals (merge overlapping intervals if necessary). Return ~intervals~/ after the insertion/. *Note* that you don't need to modify ~intervals~ in-place. You can make a new array and return it. *Example 1:* #+begin_src Input: intervals = [[1,3],[6,9]], newInterval = [2,5] Output: [[1,5],[6,9]] #+end_src *Example 2:* #+begin_src Input: intervals = [[1,2],[3,5],[6,7],[8,10],[12,16]], newInterval = [4,8] Output: [[1,2],[3,10],[12,16]] Explanation: Because the new interval [4,8] overlaps with [3,5],[6,7],[8,10]. #+end_src *Constraints:* - ~0 <= intervals.length <= 10^{4}~ - ~intervals[i].length == 2~ - ~0 <= start_{i} <= end_{i} <= 10^{5}~ - ~intervals~ is sorted by ~start_{i}~ in *ascending* order. - ~newInterval.length == 2~ - ~0 <= start <= end <= 10^{5}~ ** TODO Approach Write your approach here. ** TODO Python #+begin_src python :lc-problem 57 :lc-lang python3 class Solution: def insert(self, intervals: List[List[int]], newInterval: List[int]) -> List[List[int]]: #+end_src ** TODO C++ #+begin_src cpp :lc-problem 57 class Solution { public: vector> insert(vector>& intervals, vector& newInterval) { } }; #+end_src
