Implementation of Trie and performing Operations

#1


What is wrong with my solution ??

#2

you have done some mistakes

  1.        if(temp->children.count(ch)){
            return false;
        }else{
            temp=temp->children[ch];
        }

    this is wrong correct one is

      if(temp->children.count(ch)==0){
            return false;
        }else{
            temp=temp->children[ch];
        }

  2. in the function bool startsWith(string prefix) {
    at end you have to return true

after these modifications your code will get AC
