Swift Challenges

This is an introduction to how challenges on Edabit work. In the Code tab above you'll see a starter function that looks like this: func hello() -> String { } All you have to do is type return "hello edabit.com" between the curly braces { } and then click the Check button. If you did this correctly, the button will turn red and say SUBMIT FINAL. Click it an

Create a function that takes a number as an argument, increments the number by +1 and returns the result. Examples addition(0) ➞ 1 addition(9) ➞ 10 addition(-3) ➞ -2 Notes Don't forget to return the result. If you get stuck on a challenge, find help in the Resources tab. If you're really stuck, unlock solutions in the Solutions tab.

Write a function that takes an integer minutes and converts it to seconds. Examples convert(5) ➞ 300 convert(3) ➞ 180 convert(2) ➞ 120 Notes Don't forget to return the result. If you get stuck on a challenge, find help in the Resources tab. If you're really stuck, unlock solutions in the Solutions tab.

Create a function that takes length and width and finds the perimeter of a rectangle. Examples findPerimeter(6, 7) ➞ 26 findPerimeter(20, 10) ➞ 60 findPerimeter(2, 9) ➞ 22 Notes Don't forget to return the result. If you're stuck, find help in the Resources tab. If you're really stuck, find solutions in the Solutions tab.

Create a function that takes a number as its only argument and returns true if it's less than or equal to zero, otherwise return false. Examples lessThanOrEqualToZero(5) ➞ false lessThanOrEqualToZero(0) ➞ true lessThanOrEqualToZero(-2) ➞ true Notes Don't forget to return the result. If you get stuck on a challenge, find help in the Resources tab. If you're

There is a single operator in Swift, capable of providing the remainder of a division operation. Two numbers are passed as parameters. The first parameter divided by the second parameter will have a remainder, possibly zero. Return that value. Examples remainder(1, 3) ➞ 1 remainder(3, 4) ➞ 3 remainder(-9, 45) ➞ -9 remainder(5, 5) ➞ 0 Notes The tests only

Write a function that converts hours into seconds. Examples howManySeconds(2) ➞ 7200 howManySeconds(10) ➞ 36000 howManySeconds(24) ➞ 86400 Notes 60 seconds in a minute, 60 minutes in an hour Don't forget to return your answer.

Fix the code in the code tab to pass this challenge (only syntax errors). Look at the examples below to get an idea of what the function should do. Examples cubes(3) ➞ 27 cubes(5) ➞ 125 cubes(10) ➞ 1000 Notes READ EVERY WORD CAREFULLY, CHARACTER BY CHARACTER! Don't overthink this challenge; it's not supposed to be hard.

Create a function that takes voltage and current and returns the calculated power. Examples circuitPower(230, 10) ➞ 2300 circuitPower(110, 3) ➞ 330 circuitPower(480, 20) ➞ 9600 Notes power is voltage multiplied by current.

A student learning Swift was trying to make a function. His code should concatenate a passed string name with string "Edabit" and store it in a variable called result. He needs your help to fix this code. Examples nameString("Mubashir") ➞ "MubashirEdabit" nameString("Matt") ➞ "MattEdabit" nameString("Swift") ➞ "SwiftEdabit" Notes Don't forget to return the

Create a function that takes two integers and checks if they are equal. Examples isEqual(5, 6) ➞ false isEqual(1, 1) ➞ true isEqual(36, 35) ➞ false Notes N/A

Create a function that returns true when num1 is equal to num2; otherwise return false. Examples isSameNum(4, 8) ➞ false isSameNum(2, 2) ➞ true isSameNum(2, 3) ➞ false Notes Don't forget to return the result.

Create a function that takes an array containing only numbers and return the first element. Examples getFirstValue([1, 2, 3]) ➞ 1 getFirstValue([80, 5, 100]) ➞ 80 getFirstValue([-500, 0, 50]) ➞ -500 Notes The first element in an array always has an index of 0.

Fix the code in the code tab to pass this challenge. Look at the examples below to get an idea of what the function should do. Examples squared(5) ➞ 25 squared(9) ➞ 81 squared(100) ➞ 10000 Notes READ EVERY WORD CAREFULLY, CHARACTER BY CHARACTER! Don't overthink this challenge; it's not supposed to be hard.

Create a function that converts inches to the number of complete feet, ignoring any leftover inches. Examples inchesToFeet(324) ➞ 27 inchesToFeet(12) ➞ 1 inchesToFeet(36) ➞ 3 Notes If inches are under 12, return 0. 12 inches = 1 foot.

Create a function that finds the maximum range of a triangle's third edge, where the side lengths are all integers. Examples nextEdge(8, 10) ➞ 17 nextEdge(5, 7) ➞ 11 nextEdge(9, 2) ➞ 10 Notes (side1 + side2) - 1 = maximum range of third edge. The side lengths of the triangle are positive integers. Don't forget to return the result.

Create a function that takes a name and returns a greeting in the form of a string. Examples helloName("Gerald") ➞ "Hello Gerald!" helloName("Tiffany") ➞ "Hello Tiffany!" helloName("Ed") ➞ "Hello Ed!" Notes The input is always a name (as string). Don't forget the exclamation mark!
