//We start selection sort by scanning the entire list to
//find its smallest element and exchange it with the first
//element, putting the smallest element in its final position in
//the sorted list. Then we scan the list, starting with the second
//element, to find the smallest among the last n-1 elements
//and exchange it with the second element, putting the second
//smallest element in its final position.
//Generally, on the ith pass through the list, which we number from 0 to
//n-2, the algorithm searches for the smallest item among the n-i elements
//and swap it with A.
//After n-1 passes, the list is sorted.

package main

import (
    "fmt"
)

//Sorts a given slice by selection sort
//Input: A slice A[0..n-1] of orderable elements
//Output: The original slice after sorted in nondecreasing order
func SelectionSort(A []int) []int {

    length := len(A)

    for i := 0; i < length-1; i++ {

        min := i

        for j := i + 1; j < length; j++ {

            if A[min] > A[j] {
                min = j
            }
        }

        A[i], A[min] = A[min], A[i]
    }

    return A
}

func main() {

    A := []int{1, 10, 9, 8, 7, 44, 2, 3, 33}

    fmt.Println("The slice before sorted : ", A)
    fmt.Println("The slice after sorted : ", SelectionSort(A))
}
