DRAW MATRIX 1
Write a program that asks for a number n and then draws n*n matrice which is completely filled with ones and zeros like this:
Sample Run 1:
n-->3 // the number we get from the input file is 3
1 1 1
1 0 1
1 1 1
Input specification
There is just one number (n) in the input file showing the size of matrix. 1 ≤ n ≤ 20.
Output specification
The outer most square will be filled with ones. Then, every inner line with zeros and ones following each other.
Give a space after every digit.
Sample Run2:
n-->5 // the number we get from the input file is 5
1 1 1 1 1
1 0 0 0 1
1 0 1 0 1
1 0 0 0 1
1 1 1 1 1
Sample Run3:
n-->6 // the number we get from the input file is 6
1 1 1 1 1 1
1 0 0 0 0 1
1 0 1 1 0 1
1 0 1 1 0 1
1 0 0 0 0 1
1 1 1 1 1 1
