Answer 1

package main

import (
    "fmt"
)

func IsSquareMatrix(matrix [][]int) bool {
    length := len(matrix)

    for _, row := range matrix {
        if len(row) != length {
            return false
        }
    }

    return true
}

func main() {
    matrix := [][]int{
        {1, 2, 3},
        {4, 5, 6},
        {7, 8, 9},
    }

    if IsSquareMatrix(matrix) {
        fmt.Println("The matrix is a square matrix.")
    } else {
        fmt.Println("The matrix is not a square matrix.")
    }
}
