dre4success / mergeSort.js

Created September 19, 2018 15:37

A merge sort algorithm

	// a function that takes two arrays and merge them
	function merge(arr1, arr2){
	let i = 0
	let j = 0
	let results = []

	while (i < arr1.length && j < arr2.length) {
	if(arr2[j] > arr1[i]) {
	results.push(arr1[i])
	i++

dre4success / anagram.js

Created September 12, 2018 09:44

Giving two strings, it should return true if it's an anagram i.e a word or phrase formed by rearranging the letters of a different word or phrase, typically using all the original letters exactly once

	function anagram (str1, str2) {
	if (str1.length !== str2.length) return false
	let frequencyCounter = {}
	for (let val of str1) {
	// increment occurence of val in frequencyCounter
	frequencyCounter[val] = (frequencyCounter[val] \|\| 0) + 1
	}
	for (let val of str2) {
	if(!frequencyCounter[val]) {
	return false

Given an unsorted array of n elements, find if the element k is present in the given array or not. return 'YES' or 'NO'

{"lastUpload":"2019-07-22T17:21:44.605Z","extensionVersion":"v3.4.1"}

dre4success / isPalindrome.js

Created October 4, 2017 07:19

To return true or false if a statement is palindrome, i.e same when spelt backward

	function isPalindrome(str) {
	// convert string to lowercase
	str = str.toLowerCase();
	// convert string to an array
	let strArr = str.split('');
	// what it will be checked against to eliminitate non alphabetic characters
	let AlphabetArr = 'abcdefghijklmnopqrstuvwxyz'.split('');

	// initialize an empty array
	let newContainer = []

dre4success / fizz-buzz.js

Created October 3, 2017 19:25

number divisible by 3 outputs fizz, by 5 outputs buzz, but both outputs fizzbuzz

	const fizzBuzz = (num = 20) => {
	for(let i = 1; i <= num; i++) {
	if(i % 15 === 0) console.log('FizzBuzz');
	else if(i % 3 === 0) console.log('Fizz');
	else if(i % 5 === 0) console.log('Buzz');
	else console.log(i)
	}
	}

	fizzBuzz()

dre4success / reverse.js

Created October 2, 2017 20:41

Three ways or reversing a string

	// reversing a string with a decrementing forloop
	function reverse(str) {
	let st = "";
	for(let i = str.length - 1; i >= 0; i--) {
	st += str[i]
	}
	return st
	}

	// through a recursion

dre4success / Cassidy-Williams.js

Last active September 25, 2017 22:22

Write a function duplicate that takes in an array arr and an int n, and returns an array that duplicates arr n times

	// with loop
	function duplicate (arr, n) {
	let arry = [];

	for(let i = 0; i < n; i++) {
	arry = [...arry, ...arr]
	}
	return arry
	}
