Quantalabs / Fibbonacci Sequence.js
Created May 25, 2020 20:50
Outputs a number in the fibbonacci sequence in the console. Read about the fibbonacci sequence at https://en.wikipedia.org/wiki/Fibonacci_number
var calc = function (amount) {
var a = 1 //change the two variables to get a different fibbonacci sequence
var b = 1
for(var i = 0; i < amount; i++) {
var i = a+b
b = a
a = i
}
console.log(a) //outputs the 'amount' number in the fibbonacci sequence.
}

Quantalabs / Padovan Sequence Calc.js
Last active May 25, 2020 20:18
Outputs numbers in the Padovan Sequence. Modify the variable "amount" to change amount of numbers outputede. Read more on the Pardovan Sequence at https://en.wikipedia.org/wiki/Padovan_sequence
var list = [1,1,1] //changing these values to [3,0,2] will output the perrin sequence
var amount = 7 //changing this value will change the amount of numbers outputed.
for(var i = 0; i < amount-3; i++) { //chaning the number that is subtracted from 'amount' is the original length of list
var j = list[i];
var e = list[i+1];
list.push(j+e)
}
console.log(list) //change to 'document.body.innerHTML = list' to show on webpage or append to a div or paragraph if needed

Simple differential privacy algorithm
var flip = function (dataArray) {

var b = Math.random(0,1);
var c = Math.round(b);
if(c === 0) {
a[i] = true;
}
if(c === 1) {
var b1 = Math.random(0,1);
