SOJ 1180. Pasting Strings

This can be solved by combining the sample with the following scenarios.

The code is as follows:

1#include <iostream>2#include <stack>3#include <string>4 using namespacestd;5 6 intMain () {7     intbegin, end;8      while(CIN >> begin >> End, begin! =-1&& End! =-1) {9         stringtext;TenCin.Get(); Getline (cin, text); Onestack<string>prepend, append; A          for(intCur =0; Cur < begin; ++cur) { -             if(Text[cur] = ='<') { -                 if(Text[cur +1] =='/') { the Prepend.pop (); Append.pop (); -}Else { -                     inttail = cur +1; -                      while(Text[tail]! ='>') ++tail; +                     stringTag = text.substr (cur, tail-cur +1); - Prepend.push (tag); +Append.push (Tag.insert (1,"/")); A                 } at             } -         } -          for(intcur = begin; Cur < end; ++cur) { -             if(Text[cur] = ='<') { -                 if(Text[cur +1] =='/') { - Append.pop (); in}Else { -                     inttail = cur +1; to                      while(Text[tail]! ='>') ++tail; +                     stringTag = text.substr (cur, tail-cur +1); -Append.push (Tag.insert (1,"/")); the                 } *             } $         }Panax Notoginseng         stringAns = text.substr (begin, End-begin); -          while(!Prepend.empty ()) { theans = prepend.top () +ans; Prepend.pop (); +         } A          while(!Append.empty ()) { theAns + =append.top (); Append.pop (); +         } -cout << ans <<Endl; $     } $     return 0; -}
