**Time Complexity Guide**

~N < \infty \; \Rightarrow \; \mathcal{O}(1)~

~N \le 10^{1\,000\,000} \; \Rightarrow \; \mathcal{O}(\log{N})~

~N \le 10^{14} \; \Rightarrow \; \mathcal{O}(\sqrt{N})~

~N \le 2\times10^7 \; \Rightarrow \; \mathcal{O}(N)~

~N \le 10^6 \; \Rightarrow \; \mathcal{O}(N\log{N})~

~N \le 100\,000 \; \Rightarrow \; \mathcal{O}(N\sqrt{N})~

~N \le 5\,000 \; \Rightarrow \; \mathcal{O}(N^2)~

~N \le 1\,500 \; \Rightarrow \; \mathcal{O}(N^2\log{N})~

~N \le 500 \; \Rightarrow \; \mathcal{O}(N^2\log^2{N})~

~N \le 300 \; \Rightarrow \; \mathcal{O}(N^3)~

~N \le 70 \; \Rightarrow \; \mathcal{O}(N^4)~

~N \le 24 \; \Rightarrow \; \mathcal{O}(2^N)~

~N \le 15 \; \Rightarrow \; \mathcal{O}(3^N)~

~N \le 10 \; \Rightarrow \; \mathcal{O}(N!)~

~N \le 8 \; \Rightarrow \; \mathcal{O}(N^N)~

~2^{2^{2^2}} = 65536~
