Comparison: ACSL vs HackerRank

Case 1: Boilerplate Code Is Provided

ACSL

• Boilerplate code is already written
• Input handling is done by the system
• Output printing is done by the system
• main() method is already present
• Student only completes a specific function

Example:

class Result {
    public static String rearrangedString(String s) {
        // Write your logic here
        return s;
    }
}
    

Equivalent Case on HackerRank

• Function-based problems
• main() is hidden from the user
• HackerRank calls the function internally
• User only writes logic inside the given method

Example:

static String solve(String s) {
    // Write your logic here
    return s;
}
    

Editor Example (Case 1):

Case 2: Boilerplate Code Is NOT Provided

Raiseexamscores

• Editor is completely blank
• No boilerplate code is given
• Student must write the entire program
• Includes imports, main(), input and output

Example:

import java.util.*;

public class Main {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        int x1 = sc.nextInt();
        int y1 = sc.nextInt();
        int x2 = sc.nextInt();
        int y2 = sc.nextInt();
        int distance = Math.abs(x1 - x2) + Math.abs(y1 - y2);
        System.out.println(distance);
    }
}
    

Equivalent Case on HackerRank

• Full program challenges
• No hidden main() method
• User must write complete code
• Common in algorithms and competitive problems

Example:

import java.util.*;

public class Solution {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        // Full solution code here
    }
}
    

Editor Example (Case 2):

Summary

• Boilerplate Provided = Function-only problems (same as HackerRank function problems)
• No Boilerplate Provided = Full program problems (same as HackerRank full-code challenges)
