6. (30 points) Big-Oh and Run Time Analysis: Describe the worst case running time of the following pseudocode functions in Big-Oh notation in terms of the variable n. Showing your work is not required (although showing work may allow some partial credit in the case your answer is wrong dont spend a lot of time showing your work. Some high level explanation is good enough) You MUST choose your answer from the following (not given in any particular order) O(n), O(n2), O(n3), O(n), O(n logn) I. void silly (int n) jni while (j > 0) { System.out.printin ( " j = " + j); II. void silly (int n, int x, int y) [ for (int k n; k > 0; k--) if(x
