Problem Statement

Shuffle the characters of a string in such a way that as many of the character values are in a different position as possible. A shuffle that produces a randomized result among the best choices is to be preferred. A deterministic approach that produces the same sequence every time is acceptable as an alternative. Display the result as follows: The score gives the number of positions whose character value did not change.

Let's start with the solution:

Source code in the zkl programming language

fcn bestShuffle(str){
   s:=str.split("").shuffle();    // -->List
   if(not s) return(str,str.len()); // can't shuffle "" or "a"

   n:=str.len();
   foreach i in (n){
      foreach j in (n){
         if (i!=j and s[i]!=str[j] and s[j]!=str[i]){
	    s.swap(i,j);
	    break;
	 }
      }
   } 
   return(s.concat(), s.zipWith('==,str).sum(0));
}

ss:=T("abracadabra","immediately","grrrrrr","seesaw","pop","up","a","");
foreach s in (ss){
   ns,cnt:=bestShuffle(s);
   println("%s --> %s (%d)".fmt(s,ns,cnt));
}
