Given the code fragment: What values of x, y, z will produce the following result? 1 2 3 4 1 2 3 4 1 2 3 4 ------ 1 2 3 4 ------

The correct answer is E. X = 2, Y = 3, Z = 4. Z is for the innermost loop. Should print 1 2 3 4. So Z must be 4. Y is for the middle loop. Should print three lines of 1 2 3 4. So Y must be set 3. X is for the outmost loop. Should print 2 lines of ----. So X should be 2.

Explanation

Z is for the innermost loop. Should print 1 2 3 4. So Z must be 4. Y is for the middle loop. Should print three lines of 1 2 3 4. So Y must be set 3. X is for the outmost loop. Should print 2 lines of ----. So X should be 2.
