how to draw like 333 313 323 333 and 4444 4114 4224 4334 4444

the program should take an integer from user and print pattern like below. if n=3, then

 333
 313
 323
 333

if n=4, then

4444
4114
4224
4334
4444

if n=5, then

55555
51115
52225
53335
54445
55555

and so on

Here is what is have tried.

#include<iostream>
using namespace std;
int main()
{
    int pattern[10][10], i, j, n;
    cout << "Enter dimension of square matrix: ";
    cin >> n;
    for (i = 0;i <= n;i++)
    {
        pattern[i][0] = n;
        pattern[i][n - 1] = n;
    }
    for (j = 1;j < n - 2;j++)
    {
        pattern[0][j] = n;
        pattern[n][j] = n;
    }
    for (i = 1;i < n - 1;i++)
    {
        for (j = 1;j < n - 2;j++)
        {
            pattern[i][j] = i;
        }
    }
    for (i = 0;i <=n;i++)
    {
        for (j = 0;j < n;j++)
        {
            cout << pattern[i][j];
            cout << "\t";
        }
        cout << "\n";
    }
    return 0;
}

I am getting the right pattern but in some places, there are some garbage value (or something else)
