I will give you an integer. Give me back a shape that is as long and wide as the integer. The integer will be a whole number between 1 and 50. Example n = 3, so I expect a 3x3 square back just like below as a string: +++ +++ +++ Solution: def generate_shape(n: int) -> str: return "\n".join("+" * n for i in range(n))

Complete the function, which calculates how much you need to tip based on the total amount of the bill and the service. You need to consider the following ratings: Terrible: tip 0% Poor: tip 5% Good: tip 10% Great: tip 15% Excellent: tip 20% The rating is case insensitive (so "great" = "GREAT"). If an unrecognised rating is received, then you need to return: "Rating not recognised" in Javascript..

Code as fast as you can! You need to double the integer and return it. Solution: def double_integer(i: int) -> int: try: return i ** 2 // (i / 2) except: return 0 def doubleInteger(i: int) -> int: return i

altERnaTIng cAsE ALTerNAtiNG CaSe Define String.prototype.toAlternatingCase (or a similar function/method such as to_alternating_case/toAlternatingCase/ToAlternatingCase in your selected language; see the initial solution for details) such that each lowercase letter becomes uppercase and each uppercase letter becomes lowercase. For example: "hello world".toAlternatingCase() === "HELLO WORLD" "HE..

Can you find the needle in the haystack? Write a function findNeedle() that takes an array full of junk but containing one "needle" After your function finds the needle it should return a message (as a string) that says: "found the needle at position " plus the index it found the needle, so: Example(Input --> Output) ["hay", "junk", "hay", "hay", "moreJunk", "needle", "randomJunk"] --> "found th..

Inspired by the development team at Vooza, write the function that accepts the name of a programmer, and returns the number of lightsabers owned by that person. The only person who owns lightsabers is Zach, by the way. He owns 18, which is an awesome number of lightsabers. Anyone else owns 0. Note: your function should have a default parameter. For example(Input --> Output): "anyone else" --> 0 ..

Description: Remove all exclamation marks from sentence but ensure a exclamation mark at the end of string. For a beginner kata, you can assume that the input data is always a non empty string, no need to verify it. Examples remove("Hi!") === "Hi!" remove("Hi!!!") === "Hi!" remove("!Hi") === "Hi!" remove("!Hi!") === "Hi!" remove("Hi! Hi!") === "Hi Hi!" remove("Hi") === "Hi!" Solution: const remo..

Given an array of numbers, check if any of the numbers are the character codes for lower case vowels (a, e, i, o, u). If they are, change the array value to a string of that vowel. Return the resulting array. Solution: function isVow(a){ for (let index in a) { let vow = String.fromCharCode(a[index]) if (["a", "e", "i", "o", "u"].includes(vow)) { a[index] = vow } } return a } const isVow = a => a..

Write a method that takes one argument as name and then greets that name, capitalized and ends with an exclamation point. Example: "riley" --> "Hello Riley!" "JACK" --> "Hello Jack!" Solution: var greet = function(name) { modifiedName = name.charAt(0).toUpperCase() + name.slice(1).toLowerCase() return `Hello ${modifiedName}!` }; var greet = function(name) { return 'Hello ' + name[0].toUpperCase(..
