Sequence

Hi everyone.
I just want to ask you how to fill a multidimensional array with a sequence of numbers from 1 to n^2 provided that each number occur once.

It's hard to answer that question without just writing the code for you. Why don't you post your best effort and ask a specific question about the code?

here is a small part of code that i thought about. It is wrong!!


int num[][]=new int[5][5];
for(int i=0;i<5;i++){
for(int j=0;j<5;j++)
num[i][0]+=i;
num[0][j]+=j;
}

That code needs work. Here are a few points:

1. You wanted to store the numbers from 1 to 2**n. Where is 2**n in your code?
2. You only assign to num[i][0] and num[0][j] -- the first column and the first row.
3. Why are you using the operator "+="?
4. Always enclose a loop body in braces: {}. You didn't do that for your inner loop.
