Question

C++

Using the Stack operations, write a pseudocode routine, dupA, that takes aStack for string, checks to see if the top starts with ‘A’ or ‘a’. If so, duplicate the top of the stack (i.e. pop a copy of that value onto the stack) else if length > 10, pop it off the stack

Answer 1

Dear student, I have written both pseudocode and code. Please go through them and let me know if you have any doubts.

Pseudocode :

Code :

void dubA(stack<string> stk){
     if(stk.empty()==true)
        return ;
     else{
       tempString = stk.top();
       
       if(tempString[0] == 'A' || tempString[0] =='a'){
           stk.push(tempString);
       }else if(tempString.length()>10){
           stk.pop();
       }
     }

}

Hope you got your answer ;)
