Sorting a Two-Dimensional Array in Go

Sorting a multidimensional array can be achieved in Go by manually defining how you want the sorting to occur. Two approaches can be taken:

1. Implementing the sort.Sort Interface:

Create custom methods for Len, Less, and Swap to use with sort.Sort, enabling you to modify the array values during sorting. For example:

type Matrix [3][3]int

func (m Matrix) Len() int { return len(m) }
func (m Matrix) Less(i, j int) bool {
    for x := range m[i] {
        if m[i][x] == m[j][x] {
            continue
        }
        return m[i][x] 
2. Using the sort.Slice Function:
Convert the array to a slice and provide a comparable function for sort.Slice to handle the sorting. For instance:
sort.Slice(matrix[:], func(i, j int) bool {
    for x := range matrix[i] {
        if matrix[i][x] == matrix[j][x] {
            continue
        }
        return matrix[i][x] 
Both approaches enable you to customize the sorting behavior of your two-dimensional array in Go.
