Common time complexity

Common time complexity
4563636	o(1)	Constant order
2n+1	o(n)	Linear order
3n^2+8n+9	o(n^2)	Square order
3log(2)n+4	o(logn)	Logarithmic order
2n+3nlog(2)n+12	o(nlogn)	nlogn rank
n^3+2n^2+5n+8	o(n^3)	Cubic order
2^n	o(2^n)	Exponential order

The common time complexity is sorted from small to large ：

o(1)< o(logn)< o(n)<o(nlogn)<o(n^2)<o(n^3)< o(2^n)< o(n!)< o(n^n)
