C++ code to find string where trygub is not a substring

Suppose we have a string S with n lowercase English letters. We have to reorder the characters in S, so that "trygub" is not a subsequence of the resulting string.

So, if the input is like S = "pintontrygubabc", then the output will be "abbcginnoprttuy".

Steps

To solve this, we will follow these steps −

sort the array S
return S

Example

Let us see the following implementation to get better understanding −

#include 
using namespace std;
string solve(string S){
   sort(S.begin(), S.end());
   return S;
}
int main(){
   string S = "pintontrygubabc";
   cout 
Input
"pintontrygubabc"
Output
abbcginnoprttuy
