i am trying to take input from the using in a 2d char array where the output should be like :
110
1_0
11_
_11
0__
this can have as many combinations as 2^n where n is also user input. how can i create this output?
public static void main (String args[])
{ Scanner sc = new Scanner(System.in);
System.out.println("Enter Value i: ");
int i = sc.nextInt();
int j =(int) Math.pow(2,i);
char[][]array = new char[i][j];
for (int k=0;k<i;k++)
for (int s=0;s<j;s++)
{ array[k][s]= ?; //i am stuck here
}
Scanner scan=new Scanner(System.in);
char inputArray[][] = new char[rows][cols];
for (int i = 0; i < rows; i++)
{
for (int j = 0; j < cols; j++)
{
inputArray[i][j] = scan.next().charAt(0);
}
}
Scanner in = new Scanner(System.in);
int rows = scan.nextInt();
int cols = scan.nextInt();
char arr[][] = new char[rows][cols]; // 2D char array
for (int i = 0; i < rows; i++) {
String data = "";
if (in.hasNext()) { // input from user
data = in.next();
} else {
break;
}
for (int j = 0; j < cols; j++)
arr[i][j] = data.charAt(j);
}
// to get a 2D char array
System.out.println(Arrays.deepToString(arr));
The input will be of the form -
4 // no. of rows
5 // no. of columns
10100
10111
11111
10010
to get a 2D char array as-
[[1, 0, 1, 0, 0], [1, 0, 1, 1, 1], [1, 1, 1, 1, 1], [1, 0, 0, 1, 0]]
