Answer:
class Main {
public static void fillTable(int [][] t, int or, int oc) {
for(int r=0; r<t.length; r++) {
for(int c=0; c<t[r].length; c++) {
t[r][c] = Math.max(1+Math.abs(r-or), 1+Math.abs(c-oc));
}
}
}
public static void dumpTable(int [][] t) {
for(int r=0; r<t.length; r++) {
for(int c=0; c<t[r].length; c++) {
System.out.printf("%3d", t[r][c]);
}
System.out.println();
}
}
public static void main(String[] args) {
int origin_row = 3;
int origin_col = 2;
int[][] table = new int[5][4]; // rows|cols
fillTable(table, origin_row, origin_col);
dumpTable(table);
}
}
Explanation:
Above program does not contain input handling and exception handling, but it does contain the cleverness of calculating the cell values. I'm hoping you can add the input handling yourself?

In a real-world environment, changing granularity requirements might dictate changes in primary key selection, and those changes might ultimately require the use of surrogate keys.
Explanation:
A surrogate key is a unique identity as an object or entity. It is used as an object in the database and as an entity in the modern world. Surrogate key is not a natural key hence it cannot be derived from application data.
Advantages of using surrogate key:
- They are unique
- They have uniform rules
- It allows unlimited values
- It stands the test of time
