c++ - Sorting a map with unknown keys by value -

-

मेरे पास निम्न शैली में एक नक्शा है: 

  mapa ["01"] = 2 नक्शा ["111"] = 3   
 यह दिखाता है कि पाठ में प्रत्येक उप-स्ट्रिंग कितनी बार दिखाई देती है (पाठ में 1s और 0s होते हैं)।  
 अब हम कहते हैं कि मैं 10 सबसे अधिक बार उपयोग किए गए उप-स्ट्रिंग्स को आउटपुट करना चाहता हूं, मुझे मानचित्र में सभी चाबीओं के माध्यम से जाना होगा और उन सबसे बड़े मूल्यों के साथ मिलना होगा (मूल्य, उतरते)। कोई छद्म कोड या आज्ञाओं का उपयोग करना चाहिए?  
 अगर यह आपके लिए किसी भी उपयोग का है, तो मैं कार्य पर काम कर रहा हूं और मुझे सभी मान मिल गए हैं, मुझे नहीं पता कि उन्हें कैसे सॉर्ट करना है। / p>  
 
 
 इसे देखें, आप मूल रूप से मानचित्र को पुनरावृत्त करें और मान पर std :: partial_sort का उपयोग करें।  
  typedef std :: जोड़ी & lt; std :: string, int & gt; mypair; संरचना इंट्रकम्प {बूल ऑपरेटर () (कॉन्स्ट माइपेयर एंड एलएचएस, कंट माइपेयर एंड आरएचएस) {रिटर्न एल एच। सीकंड & gt; rhs.second; }}; शून्य प्रिंट 10 (const std :: map & lt; std :: string, int & gt; और mymap) {std :: vector & lt; mypair & gt; मैवेक (mymap.begin (), mymap.end ()); जोर दें (myvec.size ()> gt; = 10); Std :: partial_sort (myvec.begin (), myvec.begin () + 10, myvec.end (), IntCmp ()); (इंट आई = 0; आई & lt; 10; ++ i) के लिए {std :: cout & lt; & lt; मैं & lt; & lt; ":" & Lt; & lt; Myvec [i]। प्रथम & lt; & lt; "- & gt;" & lt; & lt; मैवेक [आई]। सिकेंड & lt; & lt; "\ N"; }}

I have a requirement whenever I run my own kettle, dynamically took database connection parameters from an excel source Every run should go. I have an Excel column names: hostname, username, database, password. I want to pass these connection parameters to my table input stage dynamically whenever it runs the job. This is what I was trying to do. You can get it Connection parameters from the DB reading source (for example Excel or a CSV file in my example) < / Li> Store the parameters in the variable Using the variable in your connection's settings. Setting Variables Create another conversion for (you can not do it in the same conversion Uses): set variables element variable: The element that reads / writes your data creates a new connection and sets the connection parameter using $ {variable name_} Note that you will need to type in the field field in the field $ {password} Also keep in mind that this can be a security problem as the

I am trying to implement a screen-scraps application that opens a URL in which a parameter changes as it is for a loop: var data = [ '100', '101', '102', '103', '104']; (Var indexA = 0; indexA & lt; data.length; indexA ++) for {Phantom Generation ({'port': freeport}, function (pH) {ph.create page (function (page) {page.open ("http: //...++ data [index B] +" ... " , Status {console.log ("open site:" + data [index B], position); / * OLD * / indexB ++; page evaluation (function () {// page scrape and an object Return}, function {console.log (result.dataRequest); // here is the problem}); / * new and fixed * / indexB ++} first console Logs it: Open Site: 100 Success Opens Site: 101 Success B Ola Site: 102 Success Opening Site: 103 Success Opened Site: 104 Success Which is good. Data is verified in scrap HTML and from index to array Matches. So in page 101 I scrap '101 and retrieve' and pu

I know that it can speak as a very famous topic, but something that helps me with it Not found This scenario is: I have my functions function, no matter what's inside, it's a generic function that may depend on other toolboxes. Does. Has input and output; I want to generate the same myFun.mex function; : Lib myFun This way I get some new files: libmyfun.c libmyfun.dll Libmyfun.exp libmyfun.exports libmyfun .h libmyfun.lib Reading around and I think that Creating a myfun.cpp that is very famous is included: / * gateway function * / zero max function (ent NLHS, MXARRA * PLS [], int NRHS, CONST M Xeray * PHS []) Here is the Variable Deals * / / * code here * /} I have tried to do this and are called Regular of Max Generation: Max ('- v', 'myfun.cpp') But I get many errors, and I should say that my myfun.cpp copy / Paste Function is where I have a lot of doubts ... especially on input / output management.
