What do these loops print?

a. for (int i = 1; i < 10; i++) { System.out.print(i + " "); }

b. for (int i = 1; i < 10; i += 2) { System.out.print(i + " "); }

c. for (int i = 10; i > 1; i--) { System.out.print(i + " "); }

d. for (int i = 0; i < 10; i++) { System.out.print(i + " "); }

e. for (int i = 1; i < 10; i = i * 2) { System.out.print(i + " "); }

f. for (int i = 1; i < 10; i++) { if (i % 2 == 0) { System.out.print(i + " "); } }
