Why Sorting Matters and How It Unlocks Other Algorithms

📖 Scenario: Imagine you run a small bookstore. You have a list of book prices, but they are all jumbled up. To quickly find the cheapest or most expensive book, or to check if a certain price exists, you need to sort the prices first. Sorting helps organize your data so you can do many useful things faster and easier.

🎯 Goal: You will create a list of book prices, sort them in ascending order, and then print the sorted list. This will show how sorting helps organize data and prepares it for other tasks like searching or finding minimum/maximum values.

📋 What You'll Learn

Create a slice of integers called bookPrices with the exact values: 450, 1200, 300, 700, 150

Create a variable called n that stores the length of bookPrices

Use the sort.Ints function to sort bookPrices in ascending order

Print the sorted bookPrices slice

💡 Why This Matters

🌍 Real World

Sorting prices helps store owners quickly find cheapest or expensive items, manage inventory, and prepare data for fast searching.

💼 Career

Sorting is a fundamental skill in programming and data handling, used in software development, data analysis, and many technical roles.

1

Create the list of book prices

Create a slice of integers called bookPrices with these exact values: 450, 1200, 300, 700, 150

DSA Go

# Create the slice bookPrices with the given values
# Your code here

Hint

Use bookPrices := []int{450, 1200, 300, 700, 150} to create the slice.

2

Store the length of the list

Create a variable called n that stores the length of the bookPrices slice using the len function

DSA Go

package main

func main() {
    bookPrices := []int{450, 1200, 300, 700, 150}
    // Create variable n to store length of bookPrices
    // Your code here
}

Hint

Use n := len(bookPrices) to get the length.

3

Sort the list of book prices

Use the sort.Ints function to sort the bookPrices slice in ascending order. Remember to import the sort package at the top.

DSA Go

package main

import "sort"

func main() {
    bookPrices := []int{450, 1200, 300, 700, 150}
    n := len(bookPrices)
    // Sort bookPrices in ascending order
    // Your code here
}

Hint

Use sort.Ints(bookPrices) to sort the slice.

4

Print the sorted list

Print the sorted bookPrices slice using fmt.Println(bookPrices). Remember to import the fmt package.

DSA Go

package main

import (
    "fmt"
    "sort"
)

func main() {
    bookPrices := []int{450, 1200, 300, 700, 150}
    n := len(bookPrices)
    sort.Ints(bookPrices)
    // Print the sorted bookPrices slice
    // Your code here
}

Hint

Use fmt.Println(bookPrices) to print the sorted slice.
