Any Logical people here?

Question

OK, this is for someone who knows JAVA, so others buzz off !
How exactly do I devise a code to diaplay the following pattern ?
0
0 1
1 0 1
0 1 0 1

(SORRY : That's 'display')

Answer 1

So im starting with 0 and doing n iterations... so if I want 4 lines I would put iterations=3, since the sequence will always start as 0.

String sequence = "0";
int iterations = 3; //number of lines you want at the end

System.out.println( sequence ); //sequence always start with 0
for( int n = 0; n < iterations; n++ )
{
if( n == 0 )
sequence += " 1";
else
sequence = n % 2 + " " + sequence;

System.out.println( sequence );
}

this is an O(n) algorithm.. might not look too nice but it does the work an fast.

Answer 2

int i=0,j=0,k;
for(i=0;i {
for(j=0;j<=i;j++)
{
k=j%2;
System.out.printf("%d",k);
}
System.out.printf("\n");
}

// Place this in you main method of the object.

Answer 3

you can do it in one loop and simply add the opposite of the (0,1) that was added in the last iteration

Answer 4

hint: u will have to use 2 'for' loops.
