#include <math.h>

#include <stdlib.h>

int marks_summation(int* marks, int number_of_students, char gender)  

{

 int sum = 0;

   for (int i = (gender == 'b' ? 0 : 1); i < number_of_students; i = i + 2)  

       sum += *(marks + i);

   

   return sum;

}

int main() {

   int number_of_students;

   char gender;

   int sum;

 

   scanf("%d", &number_of_students);

   int *marks = (int *) malloc(number_of_students * sizeof (int));

 

   for (int student = 0; student < number_of_students; student++) {

       scanf("%d", (marks + student));

   }

   

   scanf(" %c", &gender);

   sum = marks_summation(marks, number_of_students, gender);

   printf("%d", sum);

   free(marks);

 

   return 0;

}
