Growth	Terminology
$O(1)$	constant growth
$O(\log n)$	logarithmic growth
$O({\log }^{k}n)$ for $k\ge 1$	polylogarithmic growth
$o(n)$	sublinear growth
$O(n)$	linear growth
$O(n\log n)$	log-linear growth
$O(n{\log }^{k}n)$ for $k\ge 1$	polylog-linear growth
$O(n^k)$ for $k\ge 1$	polynomial growth
$\Omega (n^k)$ for $k\ge 1$	superpolynomial growth
$\Omega (a^n)$ for $a>1$	exponential growth
