#+PROPERTY: STUDY_DECK_02 * TODO 0213. House Robber II :medium: :PROPERTIES: :NEETCODE: [[file:../../roadmap.org::*0213. House Robber II][0213. House Robber II]] :END: You are a professional robber planning to rob houses along a street. Each house has a certain amount of money stashed. All houses at this place are *arranged in a circle.* That means the first house is the neighbor of the last one. Meanwhile, adjacent houses have a security system connected, and it will automatically contact the police if two adjacent houses were broken into on the same night. Given an integer array ~nums~ representing the amount of money of each house, return /the maximum amount of money you can rob tonight *without alerting the police*/. *Example 1:* #+begin_src Input: nums = [2,3,2] Output: 3 Explanation: You cannot rob house 1 (money = 2) and then rob house 3 (money = 2), because they are adjacent houses. #+end_src *Example 2:* #+begin_src Input: nums = [1,2,3,1] Output: 4 Explanation: Rob house 1 (money = 1) and then rob house 3 (money = 3). Total amount you can rob = 1 + 3 = 4. #+end_src *Example 3:* #+begin_src Input: nums = [1,2,3] Output: 3 #+end_src *Constraints:* - ~1 <= nums.length <= 100~ - ~0 <= nums[i] <= 1000~ ** TODO Approach Write your approach here. ** TODO Python #+begin_src python class Solution: def rob(self, nums: List[int]) -> int: #+end_src ** TODO C++ #+begin_src cpp class Solution { public: int rob(vector& nums) { } }; #+end_src
