...complexity grows is exponential.
So, we consider to be 2ⁿ, 3ⁿ, eⁿ, 2.000001ⁿ, or our n⋅2ⁿ to be same group of complexity with exponential grows.
To give it a bit mathematical sense, we consider a function f(x) to grow (not faster than) exponentially if exists such constant c > 1, tha...

var seed = 1;
function random() {
var x = Math.sin(seed++) * 10000;
return x - Math.floor(x);
