time complexity questions
what are the time complexities in these two cases, big O notation.
1.Java Code:int a =3; while (a <= n) a = a*a;
2.Java Code:public void foo (int n, int m) { int i = m; while (i > 100) i = i/3; for (int k=i ; k>=0; k) { for (int j=1; j<n; j*=2) System.out.print(k + "\t" + j); System.out.println(); } }
and the second one i'm just confused. although the general rule is that with two loops is O(n^2), but i'm assuming they're tricking us here...
