注意事项:

参考代码:

import java.util.Scanner;

public class Main {

public static void main(String[] args) {

Scanner scanner = new Scanner(System.in);

while (scanner.hasNext()) {

int m = scanner.nextInt();

int n = scanner.nextInt();

int[] arr = new int[n];

int num = 0;

for(int i=0;i<n;i++){

    arr[i] = scanner.nextInt();

    m -= arr[i];

    if(m>=0){

        num+=1;

    }

    else{

        m +=arr[i];

        continue;

    }

}

System.out.println(n-num);

}

}

}
