How to sort arrays in golang?

In Go language, you can use the sort package to sort arrays.

This package offers a variety of sorting algorithms, such as insertion sort, quicksort, and heap sort.

Below is an example of sorting an integer array in ascending order using the sort package:

package main

import (
    "fmt"
    "sort"
)

func main() {
    nums := []int{5, 2, 9, 1, 7}

    // 升序排序
    sort.Ints(nums)

    fmt.Println(nums) // 输出 [1 2 5 7 9]
}

In the above example, we first imported the sort package. Next, we created an integer array called nums, which contains some unordered integers.

Next, use the sort.Ints function to sort the array in ascending order. The sort.Ints function will modify the original array, arranging its elements in ascending order.

Finally, print the sorted array using the fmt.Println function.

In addition to the sort.Ints function, the sort package also offers other functions for sorting arrays based on different types and sorting needs. For example, the sort.Strings function is used to sort string arrays, the sort.Float64s function is used to sort arrays of float64 types, and the sort.Slice function is used for custom sorting rules. You can choose the appropriate function based on your specific sorting requirements.
