Program

import java.lang.*; import java.util.*; public class x { public static void main(String args[]) { Scanner sc = new Scanner(System.in); int n = sc.nextInt(); String s[] = new String[n+1]; int x = 0; for(int i=0;i<n;i++) { s[i] = sc.next(); if(s[i].equals("X++")) { x++; } else if(s[i].equals("++X")) { x++; } else if(s[i].equals("X--")) { x--; } else if(s[i].equals("--X")) { x--; } } System.out.println(x); } } }

Output

IP: ------------ 2 X++ --X ------------ O/P: ------------ 0 ------------
