highestScore(scores: studentsAndScores) |
it didn't pass but my answer is the simplest?
var studentsAndScores = ["Amy": 88, "James": 55, "Helen": 99]
func highestScore() {
print("\(studentsAndScores.values.max()!)")
}
highestScore()
There is no need to create a variable called temp
var studentsAndScores = ["Amy": Int(readLine()!)!, "James": Int(readLine()!)!, "Helen": Int(readLine()!)!]
func highestScore(scores: [String: Int]) {
// Store the scores and force unwrap it
let a = studentsAndScores["Amy"]!
let b = studentsAndScores["James"]!
let c = studentsAndScores["Helen"]!
// Create a nested if statement
if a > b{
if a > c{
print(a)
}
}
if b > c{
if b > a{
print(b)
}
}
if c > a{
if c > b{
print(c)
}
}
}
Here's how I solved this exercise:
//Don't change this
var studentsAndScores = ["Amy": Int(readLine()!)!, "James": Int(readLine()!)!, "Helen": Int(readLine()!)!]
func highestScore(scores: [String: Int]) {
//Write your code here.
let a = studentsAndScores["Amy"]!
let b = studentsAndScores["James"]!
let c = studentsAndScores["Helen"]!
if a > b && a > c {
print(a)
} else if b > a && b > c {
print(b)
} else {
print(c)
}
}
// List of students with their scores
var studentsAndScores = ["Amy": 10, "James": 5, "Helen": 7]
// Function that takes a dictionary as a parameter to find and print the highest score among students
func highestScore(scores: [String: Int]) {
print(studentsAndScores.values.max()!)
}
// We call the function and pass studentsAndScores dictionary as an argument
highestScore(scores: studentsAndScores) // Output: 10

//Don't change this
var studentsAndScores = ["Amy": 78, "James": 55, "Helen": 86]
func highestScore(scores: [String: Int]) {
//Write your code here.
let amyScore = scores ["Amy"]!
let jamesScore = scores ["James"]!
let helenScore = scores ["Helen"]!
}
//the result is 86 not 99, the hellen score must be changed to 86, in order to solve the challenge
