Hi jack, I'm a new to competitive programming, I saw that you stored a string input in an array of integer spreated by space inside for loop. I'm confused with that specific part. Could you please help me with that?

Hi monick,
This particular program is for the below question on codeforces site
https://codeforces.com/problemset/problem/231/A
Please refer to the above site and you will understand the question, for that question this program is a solution.(then you will understand wht I am storing the inputs in to an array of integer)

Hi @Jack-Saleem, i tried my own code and was like this, but didn't know why the compiler accepts yours and not mine, can you tell?
`import java.util.Scanner;

public class Team {
//program on codeforces.com
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
Scanner scanner2 = new Scanner(System.in);
int n = scanner.nextInt();
int arr[] = new int[n];
int count, fin = 0;

	if (n >= 1 && n <= 1000) {
		//loop for problems num
		for (int i = 0; i < arr.length; i++) {
			String[] arrItems = scanner2.nextLine().split(" ");
			count = 0;
			//loop for player num
			for (int j = 0; j < 3; j++) {
				int arrItem = Integer.parseInt(arrItems[j]);
				int x = arrItem;
				if (x == 1) 
					count++;
			}
			if (count >= 2) {
				fin++;
			}
		}
	}
	System.out.println(fin);
	scanner.close();
}

}`

import java.util.Scanner;

public class CodeForces {

public static void main(String[] args) {
    Scanner sc = new Scanner(System.in);
    int n = sc.nextInt();
    int count = 0 ;
    for (int i = 0; i < n; i++) {
        int a = sc.nextInt();
        int b = sc.nextInt();
        int c = sc.nextInt();
        if ((a ==1 && b == 1) || (a ==1 && c == 1) || (b ==1 && c == 1)) 
            count ++ ; 

    }
    System.out.println(count);
}

}

import java.util.Scanner;

public class CodeForces {

public static void main(String[] args) {
    Scanner sc = new Scanner(System.in);
    int n = sc.nextInt();
    int count = 0 ;
    for (int i = 0; i < n; i++) {
        int a = sc.nextInt();
        int b = sc.nextInt();
        int c = sc.nextInt();
        if ((a ==1 && b == 1) || (a ==1 && c == 1) || (b ==1 && c == 1)) 
            count ++ ; 

    }
    System.out.println(count);
}

}

import java.util.*;

public class TwohundthrityoneA {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
int n=sc.nextInt();
int count =0; // to count result
for(int i=0;i<n;i++){
int idcount=0; // for indiviual dicision

        int a = sc.nextInt();
        if(a==1){
            idcount++;
        }

        int b = sc.nextInt();
        if(b==1){
            idcount++ ;
        }
        int c = sc.nextInt();
        if(c==1){
            idcount++ ;
        }
        if(idcount>=2){
            count++ ;
        }
      }
     System.out.println(count);

     sc.close();
     }
}

here is my code for this problem hope helps
