java - How to count the occurrence of an element in a tree? - 


  सार्वजनिक int countOccurrences (स्ट्रिंग लक्ष्य) {int count = 0; नोड कर्सर = रूट; जबकि (कर्सर! = नल) {int compare = target.compareTo (cursor.word); अगर (तुलना करें == 0) {//System.out.println("aa "); यहां पर अटक गया ++; } और अगर (तुलना & gt; 0) कर्सर = कर्सर। राइट; और कर्सर = कर्सर। बाएं; } System.out.println (गणना); वापसी की गणना; }

मुझे एक शब्द की घटनाओं को एक पेड़ में ढूंढना है (जो पहले से ही एक शब्दकोष के क्रम में किया गया है)। मेरा कोड अब स्क्रीन पर "एए" को प्रिंट कर रहा है ... मदद?

आप नहीं हैं अपने बयान में बदलकर कर्सर, आप केवल गिनती बदल रहे हैं, जिसका कर्सर पर कोई प्रभाव नहीं पड़ता है ताकि आप अनंत लूप में फंस जाएं। जब आप एक मैच पाते हैं और बढ़ते गिनती के लिए आपको कर्सर बदलना होगा। उदाहरण के लिए नीचे देखें: 

  यदि (तुलना करें == 0) {//System.out.println("aa "); यहां पर अटक गया ++; कर्सर = कर्सर। बाइट}

यह माना जाता है कि जिस तरह से यह सॉर्ट किया गया है, वह कुछ बाएं शाखा में होगा बस इसके विपरीत cursor.left को cursor.right में परिवर्तित करें।

Django Celery - running scheduled tasks -

After several hours on this without the result, I really need help I'm able to run Django-Celery with my Django app and I scheduled tasks on it: dragon manage.py celeryd -E -B -l INFO Now it is time to produce and here it is that my pain begins. I have configured the cellarid as the daemon, it works, but scheduled tasks will not work. So I added -b to CELERYD_OPTS . My tasks are now run as scheduled, but these are the boring lines on my logs: [2014-02-17 22: 37: 30,738: debuts / main process] Beat: 5.00 Waking in seconds I just want to delete that line from my logs! I did not even understand what it meant. So I had configured the Selerbeat daemon, thinking it would be a cleaner and suggest a solution to the production environment. Unfortunately, when I stop the celerybeat daemon, it creates a log and a PID file but scheduled tasks do not work. Info / main process] green: ... [2014-02-17 19: 15: 41,921: information / main process] write entries. .. [...
