Created Oct 10, 2019
You need to check all the usernames in a database. Here are some simple rules that users have to follow when creating their username. 1) The only numbers in the username have to be at the end. There can be zero or more of them at the end. 2) Username letters can be lowercase and uppercase. 3) Usernames have to be at least two characters long. A …

nickihastings / pairwise.js
Created Apr 17, 2018
Given an array arr, find element pairs whose sum equal the second argument arg and return the sum of their indices. If multiple pairs are possible that have the same numeric elements but different indices, return the smallest sum of indices. Once an element has been used, it cannot be reused to pair with another. For example pairwise([7, 9, 11, …

function pairwise(arr, arg) {
//if its an empty array return 0
if(arr.length === 0){
return 0;

//reduce the array by looping over the array and checking if the
//sum of the current element and another element = the argument.
//if they match and the indexes of both are different, add the indexes to
//the output array.

Created Apr 17, 2018
Return a new array that transforms the element's average altitude into their orbital periods. The array will contain objects in the format {name: 'name', avgAlt: avgAlt}. You can read about orbital periods on wikipedia. The values should be rounded to the nearest whole number. The body being orbited is Earth. The radius of the earth is 6367.4447…

function calcPeriod(avgAlt){
var orbitalRadius = earthRadius + avgAlt;
//calculation is 2 multiplied by pi multiplied by the square root of the
//orbital radius to the power of 3 divided by the GM
var period = Math.round(2*Math.PI*(Math.sqrt(Math.pow(orbitalRadius,3)/GM)));

The methods that take an argument must accept only one argument and it has to be a string. These methods must be the …

Return the number of total permutations of the provided string that don't have repeated consecutive letters. Assume that all characters in the provided string are each unique. For example, aab should return 2 because it has 6 total permutations (aab, aab, aba, aba, baa, baa), but only 2 of them (aba and aba) don't have the same letter (in this c…
