areagray / thirdGreatest.js

Created January 21, 2014 22:27

Coderbyte: Have the function ThirdGreatest(strArr) take the array of strings stored in strArr and return the third largest word within in. So for example: if strArr is ["hello", "world", "before", "all"] your output should be world because "before" is 6 letters long, and "hello" and "world" are both 5, but the output should be world because it a…

	//Coderbyte

	function ThirdGreatest(strArr) {
	var matrix=[];

	//build the array, two dimensions
	for (var i=0; i<strArr.length;i++){

	matrix.push([strArr[i].length,strArr[i]]);

areagray / numberAddition.js

Created January 19, 2014 19:01

Coderbyte: Have the function NumberSearch(str) take the str parameter, search for all the numbers in the string, add them together, then return that final number. For example: if str is "88Hello 3World!" the output should be 91. You will have to differentiate between single digit numbers and multiple digit numbers like in the example above. So "…

	//coderbyte

	function NumberAddition(str) {
	var mathches,
	total=0;

	// use regexp to grab the numbers
	matches=str.match(/([\d]+)/g);

	//itereate and add

areagray / swapCase.js

Last active September 27, 2022 08:42

Coderbyte: Have the function SwapCase(str) take the str parameter and swap the case of each character. For example: if str is "Hello World" the output should be hELLO wORLD. Let numbers and symbols stay the way they are.

	//coderbyte

	function SwapCase(str) {
	var newChar='',
	newString='';

	newString = str.replace(/./g, function(myChar){

	//use the replace to iterate and rebuild string
	if (myChar.match(/[a-z]/)){

areagray / dashInsert.js

Created January 18, 2014 17:20

Coderbyte: Have the function DashInsert(num) insert dashes ('-') between each two odd numbers in num. For example: if num is 454793 the output should be 4547-9-3. Don't count zero as an odd number.

	//coderbyte

	function DashInsert(num) {

	var prev='',
	newstring='';

	num = num.toString();

	for (var i=0; i<num.length; i++){

areagray / meanMode.js

Created January 14, 2014 17:02

Using the JavaScript language, have the function MeanMode(arr) take the array of numbers stored in arr and return 1 if the mode equals the mean, 0 if they don't equal each other (ie. [5, 3, 3, 3, 1] should return 1 because the mode (3) equals the mean (3)). The array will not be empty, will only contain positive integers, and will not contain m…

	//Coderbyte

	function MeanMode(arr) {
	var sum=0,
	mean, mode, midpoint, modeStr, re,
	champTotal=0;

	//old faithful
	arr.sort(function(a, b) {
	return a - b;

areagray / countingMinutes1.js

Created January 14, 2014 15:27

Coderbyte: Using the JavaScript language, have the function CountingMinutesI(str) take the str parameter being passed which will be two times (each properly formatted with a colon and am or pm) separated by a hyphen and return the total number of minutes between the two times. The time will be in a 12 hour clock format. For example: if str is 9:…

	//Coderbyte Challenge

	function CountingMinutesI(str) {

	var when,
	offset,
	mins,
	segments = [],
	ampm,
	hours,

areagray / divisionStringified

Created January 14, 2014 04:25

Coderbyte: Using the JavaScript language, have the function DivisionStringified(num1,num2) take both parameters being passed, divide num1 by num2, and return the result as a string with properly formatted commas. If an answer is only 3 digits long, return the number with no commas (ie. 2 / 3 should output "1"). For example: if num1 is 123456789 …

	//Coderbyte DivisionStringified

	function DivisionStringified(num1,num2) {
	//divide, round, convert
	var result = x = Math.round(num1/num2).toString();
	var groups =[];

	//section out 3 digits at a time from end
	while (result.length>3){
	pusher=result.slice(result.length-3,result.length);

areagray / secondGreatLow.js

Coderbyte Challenge SecondGreatLow

	/* Coderbyte Challenge

	Using the JavaScript language, have the function SecondGreatLow(arr) take the array of numbers stored in arr
	and return the second lowest and second greatest numbers, respectively, separated by a space.
	For example: if arr contains [7, 7, 12, 98, 106] the output should be 12 98.
	The array will not be empty and will contain at least 2 numbers.
