As I did on my previous post I will continue to show you some of my solution on various kata that I solved. Let's start: Count cubes in a Menger Sponge Task In this kata you will create a function that takes non negative integers (from 0 to n) and return the amount of cubes that the Menger Sponge would have in that specific iteration Example calc_ms(0) == 1 calc_ms(1) == 20 calc_ms(2) == 400 calc_ms(3) == 8000 calc_ms(4) == 160000 calc_ms(5) == 3200000 calc_ms(6) == 64000000 My solution was an online solution: function calc_ms(n) { return Math.pow(20,n) } Remove First and Last Character Task It's pretty straightforward.

Add an wysiwyg-editor on your angular app
