Random Problem Set

Do as many of these as makes sense to you to do. They vaguely progress from easy to hard. They should only need variables/if-else statements/for or while loops to complete.

func print1to4() {

// this function should print 1 2 3 4 three different ways

// method #1 using a single print statement and no loop

// method #2 using a four print statements

// method #3 using a single print statemnt and a loop

// In comments in the function, discuss the pros/cons to each approach

}

func printStatsFor(number1 : Int, number2 : Int, number3 : Int) {

// this function should take in 3 numbers and print the following

// sum of the three numbers

// average of the three numbers

// product of the three numbers

// smallest of the three numbers

// largest of the three numbers

}

func isOdd(number : Int) -> Bool {

// this functions should return true if the number is odd, and false if the number provided is even

}

func printSquaresAndCubesTable(to number: Int) {

// this function should calculate and print the squares from 1 to number. // Ex print with number = 5

// Note! Dont use any functions to find the powers, just use the arithmatic weve covered so far

}

func raise(_ number : Int, toThePowerOf exponent: Int) -> Int {

// this function should take number and multiply it to itself exponent times

// raise(2, toThePowerOf: 3) should return 8

// raise(1, toThePowerOf: 20) should return 1

// raise(10, toThePowerOf: 3) should return 1000

}

func isAPalindrome(number: Int) -> Bool {

// this function should take in a 5 digit integer, and return true if the number would be the same if the digits were reversed, and false if it would make a new number

// ex:

// isAPalindrome(number: 12321) should return true

// isAPalindrome(number: 55555) should return true

// isAPalindrome(number: 12361) should return false

}

func binaryToInt(_ binaryString : String) -> Int {

// this function should take in a string of 1s and 0s and turn it into the equivalent decimal number

// If youre not farmiliar with binary, this is a great time to learn about it!

// here are a few examples to get you started

// binaryToInt(0) -> 0

// binaryToInt(1) -> 1

// binaryToInt(10) -> 2

// binaryToInt(11) -> 3

// binaryToInt(100) -> 4

// binaryToInt(101) -> 5

// binaryToInt(110) -> 6

// binaryToInt(111) -> 7

// binaryToInt(1000) -> 8

// binaryToInt(1001) -> 9

// binaryToInt(1010) -> 10

// binaryToInt(1011) -> 11

// binaryToInt(1100) -> 12

// binaryToInt(1101) -> 13

// binaryToInt(1110) -> 14 // binaryToInt(1111) -> 15

}

func printACheckerboard() {

// print the following pattern using only one of each of these statements: print(*, terminator: ), print( , terminator: ), print()

}

func printTriangles(height : Int) {

//print the patterns shown here ->

// (shown are height = 5)

}
