java - Time and space complexity of this function to print binary tree level by level -

-

this algorithm printing common binary tree level level.

what time complexity , space complexity of printspecificlevel_bt() , printbt_lbl()?

i think printspecificlevel_bt's time complexity o(lg n), , space complexity o(lg n).
think printbt_lbl()'s time complexity o((lgn)^2), , space complexity o((lgn)^2).

is correct?

// print specific level of binary tree. public static void printspecificlevel_bt (node root, int level) {     if (root == null) return;     if (level == 0) system.out.print(string.format("%-6d", root.data)); // base case.     // recrusion.     printspecificlevel_bt(root.leftch, level - 1);     printspecificlevel_bt(root.rightch, level - 1); }  // height of binary tree. public static int getheight_bt (node root) {     if (root == null || (root.leftch == null && root.rightch == null)) return 0; // base case.     return 1 + math.max (getheight_bt(root.leftch), getheight_bt(root.rightch)); }  // print binary tree level level. public static void printbt_lbl (node root) {     // height of binary tree.     int height = getheight_bt(root);     (int = 0; <= height; ++) {         printspecificlevel_bt(root, i);         system.out.println();     } }

printspecificlevel_bt o(n) since looks @ every node in tree. however, change (returning when level == 0), can make o(min(n, 2^level)).

getheight o(n) since looks @ every node in tree. printbt_lbl calls getheight once , printspecificlevel_bt height times, complexity o(n + n*height) = o(n*height).

the space complexity of each o(height) since recurses way bottom of tree. can't o(log n) since tree isn't balanced (unless is).

Change the color of an oval at click in Java AWT -

i have draw ovals in java, , @ click change color. beginning tried change color after 20 ms, doesn't work. my code is: public class mycomponentnew extends frame { public graphics2d g2d; public mycomponentnew(string title) { super(title); setsize(400, 550); } @override public void paint(graphics g) { this.g2d = (graphics2d) g; this.g2d.setcolor(color.red); this.g2d.filloval(10, 55, 50, 100); } public void changecolor () { this.g2d.setcolor(color.blue); this.g2d.filloval(10, 55, 50, 100); } } and in class main method have: mycomponentnew m; m = new mycomponentnew("fereastra cu baloane"); m.setvisible(true); m.addwindowlistener(new windowadapter() { @override public void windowclosing(windowevent we) { system.exit(0); } }); try { thread.sleep(20); } catch(interruptedexception e) {} m.changecolor(); the color of oval remains red. ...
