As suggested you can use sort #include <iostream> #include <vector> #include <algorithm> using namespace std; int main () { std::vector<string> vec={“abc”,”defsf”,”a”,”c”}; cout<<“Unsorted string”<<endl; for(auto s: vec) { cout<<s<<” “; } std::sort(vec.begin(),vec.end(),[](const string& a,const string& b) { return a.size()<b.size(); }); cout<<endl<<“Sorted string”<<endl; for(auto s: vec) { cout<<s<<” “; } return 0; } solved how to sort … Read more
Use regex /r\d+=\d+/: “http://test.com?t&r12=1&r122=1&r1=1&r124=1”.scan(/r\d+=\d+/) # => [“r12=1”, “r122=1”, “r1=1”, “r124=1”] “http://test.com?t&r12=1&r124=1”.scan(/r\d+=\d+/) # => [“r12=1”, “r124=1”] You can use join to get a string output. Here: “http://test.com?t&r12=1&r122=1&r1=1&r124=1”.scan(/r\d+=\d+/).join(‘,’) # => “r12=1,r122=1,r1=1,r124=1” Update If the URL contains other parameters that may include r in end, the regex can be made stricter: a = [] “http://test.com?r1=2&r12=1&r122=1&r1=1&r124=1&ar1=2&tr2=3&xy4=5”.scan(/(&|\?)(r+\d+=\d+)/) {|x,y| a << … Read more
