public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
int[] H = new int[10];
for(int i = 0; i < 10; i++){
int x = sc.nextInt();
H[i]= x;
}
Scanner sc2 = new Scanner(System.in);
int height = sc2.nextInt();
int count=0;
for(int i=0;i<10;i++){
if(height+30>=H[i]) count++;
}
System.out.print(count);
}为什么是0??
