java - How to print elements from a binary tree ignoring all the repeating ones? - 


  सार्वजनिक शून्य प्रिंटट्री (नोड रूट) {if (root! = Null) {printTree (root.left); System.out.print (रूट.वर्ड + "" + रूट.लाइन + ""); स्ट्रिंग tempStr = root.word; Int tempLn = root.line; // यह कैसे उपयोग करने के लिए पता नहीं printTree (root.right); }}

मान लें कि पेस्ट को पहले से ही किसी शब्दकोष के क्रम में क्रमबद्ध किया गया है।

उदाहरण के लिए, फ़ाइल इस तरह है:

Aaa

zzz

और आउटपुट की तरह होना चाहिए:

एएए लाइन : 1

लाइन: 3 3 3 3

zzz रेखा: 2

मेरा कोड अब कई बार एक ही शब्द प्रदर्शित करता है .. मुझे नहीं पता कि इस कोड को कैसे व्यवस्थित करें ..

समस्या यह है कि आप तुरन्त हैं जानकारी को आउटपुट करने पर आपको यह पता चलता है। इसके बजाय, आपको एक निरंतर फैशन में आने वाले डेटा को संग्रहित करने की आवश्यकता होती है।

आप संभवत: एक हैशमैप & lt; स्ट्रिंग, लिस्ट & lt; Integer & gt; & gt; डेटा संरचना का उपयोग करना चाहते हैं इस जानकारी को रखें।

c# - Reactive Extensions ControlScheduler -

Well, I'm using Reactive Extension Event Handler to handle my app events, I run the headlines on the Yuri thread. I also use ControlSubular for However, recently I am getting cross thread exception despite using control scheduler and I do not know what the problem is. Code: Observable.FromEventPattern & Lt; String & gt; (CC, "UiAlertMessage", New Control Session ()) Subscribe (_ = & gt; {Alert Control. (Show this language, title, _.EventArgs.UppercaseFirst ());}); The new control scheduler (this) is not to run the code on the UI control thread, so I do not get cross threading exceptions? you should do Observable.FromEventPattern & lt; String & gt; (CC, "UiAlertMessage"). AboveOption (this). Subscribe (_ = & gt; {Alert Control. (Show this language, Titles, _.EventArgs.UppercaseFirst ());}); This is the standard way of sending a scheduler related to specific controls. Passing control scheduler as you have got subsc...

scala - Play Framework - how to bind form to a session field -

Is there any way, I can get some parameters from the header, cookies (log in userId in my case) , And then apply it in a form which I know who will deposit the ticket?

It could Ript, but the issue may be re-used in any way to verify and return the form, it can not be sure how it ....

c++ - Why does Visual Studio Release build break on non-executing code line -

When I created my C ++ program with the default release configuration in Visual Studio 10, I put a breakpoint on one line Who should never be reached. What confunded me was that when the program is running then it stopped at the breaking point. Adding a volatile statement and transferring this line to the break point does not break the execution of the code where the brake appears (though does not produce the same behavior as creating a minimum project with this function). Why is the "Release Debugger" (?) Step on this line and when executing breakpoints are executed? If I keep going after the break then false statement continues to return code execution. bool bounding box :: Cutting (int32_t xpos, int32_t ypos, int32_t dx, int32_t dy) const {int32_t intersectionX; Int32_t intersections; If ((dx> 0 & amp; amp; and & amp; xpos> rights) || (dx gt; Top) || (D & LT; 0 & amp; AOPO & Lt; BOT)) Return; If (DX! = 0) {intersection Y = ypos + (left...
