Recursion-1 > stringClean
prev  |  next  |  chance

Given a string, return recursively a "cleaned" string where adjacent chars that are the same have been reduced to a single char. So "yyzzza" yields "yza".


stringClean("yyzzza") → "yza"
stringClean("abbbcdd") → "abcd"
stringClean("Hello") → "Helo"

...Save, Compile, Run (ctrl-enter)

public String stringClean(String str) { }
