using System;
 
class GFG{
 
/* Searches the element x in mat[][]. If the 
element is found, then prints its position 
and returns true, otherwise prints "not found"
and returns false */  
static int search(int[,] mat, int n, int x)
{
    if (n == 0)
        return -1;
     
    // Traverse through the matrix
    for(int i = 0; i < n; i++) 
    {
        for(int j = 0; j < n; j++)
         
        // If the element is found
        if (mat[i,j] == x) 
        {
            Console.Write("Element found at (" + i +
                          ", " + j + ")\n");
            return 1;
        }
    }
    Console.Write(" Element not found");
    return 0;
