0198 House Robber

Question

My Solution:

class Solution {
    public int rob(int[] nums) {
        int rob1 = 0, rob2 = 0;

        // [rob1, rob2, n, n+1, ...]
        for(int n : nums){
            int temp = Math.max(n + rob1, rob2);
            rob1 = rob2;
            rob2 = temp;
        }

        return rob2;
    }
}
