मैंने abc 

  a1.b1.c1 a1.b1 नीचे स्ट्रिंग सेट किया है .c2 a1.b2.c3 a2.b1.c1 a2.b2.c2 a3.b3.c3   
 अगर  a1। *  के लिए पूछा जाए तो मुझे वापस कर देना चाहिए  a1  से शुरू होने वाली सभी स्ट्रिंग यदि  a1.b1  के लिए पूछा गया है, तो सभी कोड को  a1.b1  से शुरू कर देना चाहिए  
 सभी आउटपुट सॉर्ट किए गए फ़ैशन में होंगे (लेक्सिकोग्राफिक)  
 डेटास्ट्रक्चर पर कोई सुझाव, मैं  प्रत्यय वृक्ष  की सोच रहा था।   
 
 
 यह कोड आपकी मदद कर सकता है।  
  स्ट्रिंग स्ट्रैररे [] = {"A1.b1.c1", "a1.b1.c2", "a1.b2.c3", "a2.b1.c1", "a2.b2.c2", "a3.b3.c3"}; स्ट्रिंग आरम्भ से = "a1.b1"; के लिए (int i = 0; i & lt; stringarray.length; i ++) {if (स्ट्रैर्रे [i]। Starsts (withfrom)) system.out.println ("स्ट्रिंग है:" + stringarray [i]); }

excel vba - How to delete Solver(SOLVER.XLAM) code -

-
After opening several examples of macro / code written, I suddenly get stuck with a code that seems safe. Solver (SOLVER.XLAM) is doing this notation and I would like to remove it from my system. I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.
