else
System.out.print (" " + k);

Why is the answer k%3?

Do you know what is the % operator?

if (x == 5 || y > 2) is fully equivalent to if ( ! ( ________________ ) )

Why is the answer x != 5 && y <= 2

Do you know De Morgan's laws? (hint: search on Wikipedia)

This is inherent to boolean algebra.

Complete this if-statement (you may use else) to assign to x the smaller of y and z:

if (y < z) ________________ ;

Why is the answer x = y; else x = z

If y is lower than z, what is the smaller? And otherwise?
