Question

A ceremony where a Bride chooses her Groom from an array of eligible bachelors is called Swayamvar. But this is a Swayamvar with difference. An array of Bride-to-be will choose from an array of Groom-to-be.

Answer 1

Answer:

package Arrays;

import java.util.*;

public class Swayamvar {

public static void main(String[] args) {

 Scanner scn = new Scanner(System.in);

 int n = scn.nextInt();

 String BrideChoice = scn.next();

 String GhroomChoice = scn.next();

 int brLen = n;

 for(int i = 0; i < n; i++) {

  boolean condition = false;

  int loop = brLen;

  for(int j = 0; j < loop; j++) {

   //removing character from string

   if(BrideChoice.charAt(0) == GhroomChoice.charAt(j)) {

    BrideChoice = charRemoveAt(BrideChoice, 0);

    GhroomChoice = charRemoveAt(GhroomChoice, j);

    brLen -= 1;

    condition = true;

    break;

   }

   

  }

  if(condition == false) {

   break;

  }

 }

 

 System.out.println(brLen);

}

 public static String charRemoveAt(String str, int p) {  

//   System.out.println(str.substring(0, p) + str.substring(p + 1));

        return str.substring(0, p) + str.substring(p + 1);  

     }  

}
