Solution 1:
import java.util.*;
import java.util.Scanner;
public class A282 {
public static int calculateFinalValue(int n, Scanner scn) {
int ans = 0;
for (int i = 0; i < n; i++) {
String operation = scn.next();
if (operation.contains("+")) {
ans++;
} else {
ans--;
}
}
return ans;
}
public static void main(String[] args) {
Scanner scn = new Scanner(System.in);
int n = scn.nextInt();
System.out.println(calculateFinalValue(n, scn));
scn.close(); // Always close the scanner to avoid resource leaks
}
}
