Problem Trolls are attacking your comment section! A common way to deal with this situation is to remove all of the vowels from the trolls’ comments, neutralizing the threat. Your task is to write a function that takes a string and return a new string with all vowels removed. For example, the string “This website is for losers LOL!” would become “Ths wbst s fr lsrs LL!”. Solution Solution 1 (defn disemvowel string) Solution 2 (defn disemvowel string)
Problem: Write a function to calculate fibonacci number in constant space complexity. (defn fib n)
From today, I will practice one programming kata per day and post the content here. Here goes the first one: My friend John likes to go to the cinema. He can choose between system A and system B. System A : buy a ticket (15 dollars) every time System B : buy a card (500 dollars) and every time buy a ticket the price of which is 0.90 times the price he paid for the previous one.
Table of Contents 1. Problem 2. Analysis 3. Source Code 4. Build script 5. How to run I suck at algorithms, even though I have a Machine Learning and Algorithms master degree. It makes me frown everytime in coding interviews. So I decided to practice more often, hope that I can get better at it. At least not afraid of it. Now this is the first one.
