Write a Program to find the transpose a matrix

For example

Input:
[1,2,3]
[4,5,6]
[7,8,9]

Output:
[1,4,7]
[2,5,8]
[3,6,9]

Solution:

using System;

namespace TransposedMatrix
{
    class Program
    {
        static void Main()
        {
            int[,] a = {
                {1, 2, 3},
                {4, 5, 6},
                {7, 8, 9}
            };

            var rows = a.GetLength(0);
            var cols = a.GetLength(1);

            var t = new int[cols, rows];

            for (var i = 0; i < cols; i++)
            {
                for (var j = 0; j < rows; j++)
                {
                    t[i, j] = a[j, i];
                }
            }

            Console.WriteLine("Transposed matrix: ");
            for (var i = 0; i < cols; i++)
            {
                for (var j = 0; j < rows; j++)
                {
                    Console.Write(t[i, j] + "\t");
                }
                Console.WriteLine();
            }

            Console.ReadLine();
        }
    }
}
