Question

(java)

Working with two variables:

playernum and winningnum

player number is the number the user imputs

win num is the winning number(s) to win a prize

when the playnum matches the winnum in any order of 3 digits (123 matches 321, 456 matches 654)

a prize is won.

how can i make a method that computes this without substrings, indexof,

only boolean/ if/else statements

I'm not sure where to start or what to use

Answer 1

import java.util.*;
public class calculate
{
static void Compute_winner(int playernum, int winningnum)
{
int rev_num = 0;
while(playernum > 0)
{
rev_num = rev_num * 10 + playernum % 10;
playernum = playernum / 10;
}
if(rev_num==winningnum)
{
System.out.println("Player win!");
}
else
System.out.println("Player loos!");
}
  
// Driver code
public static void main (String[] args)
{
Scanner in=new Scanner(System.in);
System.out.println("Entter playernum: ");
int playernum=in.nextInt();
System.out.println("Entter winningnum: ");
int winningnum=in.nextInt();
Compute_winner(playernum,winningnum);
}
}

Entter playernum: 123 Entter winningnum: 321 Player win!
