i need fix previous code. if input "aabbcdefgghijkllaa", output needs "abcdefghijkla". current code have changed outputs "alkjihgfedcba". (the input may not in alphabetical order, , output should in same order original input.) should create new method reverse or there way fix current methods? here code: package recursion; public class recursion { static string = "aabbcdefgghijkllaa"; static int b=a.length()-1; static string result = ""; public static void main(string[] args){ system.out.println("input: " + a); system.out.print("output: "); removeduplicates(a); } public static string removeduplicates(string a){ if (b <= 0){ system.out.print(a.charat(0)); result=result+a.charat(0); } else if (a.charat(b) == a.charat(b-1)) { b--; removeduplicates(a); } els...

here y values: [1.00, [(1.99-2.27e-17j),(0.61+9.08e-17j), (0.12-0j)], [(1.9+4.54e-17j), (0.61-9.081e-17j), (0.12+4.54e-17j)], [(1.99+4.5e-17j), (0.61-9.08e-17j), (0.12+4.54e-17j)], [(1.99-2.27e-17j), (0.61+9.0e-17j), (0.12-0j)], 3.00] and here x values: array([ 0. , 0.2, 0.4, 0.6, 0.8, 1. ]) as can see, first , last x values correspond 1 y value , rest of x values correspond multiple y values. how plot real part of y values against x ? here solution might you. note isn't efficient (especially problem bigger datasets), might put on right track. main issue dimensionality between xs , ys not same. from numpy import * matplotlib import pyplot plt ys = [1.00, [(1.99-2.27e-17j),(0.61+9.08e-17j), (0.12-0j)], [(1.9+4.54e-17j), (0.61-9.081e-17j), (0.12+4.54e-17j)], [(1.99+4.5e-17j), (0.61-9.08e-17j), (0.12+4.54e-17j)], [(1.99-2.27e-17j), (0.61+9.0e-17j), (0.12-0j)], 3.00] xs = array([ 0. , 0.2, 0.4, 0.6, 0.8, 1. ]) pxs = [] pys = [] i, yelems...

i want chrome windows running currently. below code windows. final windef.hwnd[] windowhandle = new windef.hwnd[1]; user32.instance.enumwindows(new winuser.wndenumproc() { @override public boolean callback(windef.hwnd hwnd, pointer pointer) { if (matches(hwnd)) { windowhandle[0] = hwnd; return false; } return true; } }, pointer.null); how can running chrome windows ? i think better use completed third party library sigar. https://support.hyperic.com/display/sigar/home you api work processes. @ least can @ source code. sigar sigar = new sigar(); processfinder find = new processfinder(sigar); find.find("exe.name.ct=chrome");
