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.

a) int silly(int n, int m) {

if (m < 2) return m;

if (n < 1) return n;

else if (n < 10)

return silly(n/m, m);

else

return silly(n - 1, m);

} __________________

b) void silly(int n, int x, int y) {

if (x < y) {

for (int i = 0; i < n; ++i)

for (int j = 0; j < n * i; ++j)

System.out.println(y = + y);

} else {

System.out.println(x = + x);

}

} __________________

c) void silly(int n) {

j = 0;

while (j < n) {

for (int i = 0; i < n; ++i) {

System.out.println(j = + j);

}

j = j + 5;

}

} __________________

d) void silly(int n) {

for (int i = 0; i < n * n; ++i) {

for (int j = 0; j < n; ++j) {

for (int k = 0; k < i; ++k)

System.out.println(k = + k);

for (int m = 0; m < 100; ++m)

System.out.println(m = + m);

}

}
