Question

This a java program.

The Riddler is planning his next caper somewhere on Pennsylvania Avenue. In his usual sporting fashion, he has left the address in the form of a puzzle. The address on Pennsylvania is a four digit number where: -All four digits are different -The digit in the thousands place is three times the digit in the tens place -The number is odd -The sum of the digits is 27 This is a java program Write a program that uses a loop (or loops) to find the address where the Riddler plans to strike.

Answer 1

class Riddler{
public static void main(String [] args){
   int i,j=0,k=0,l=0;
       int flag = 0;
       for(i=1 ;i<10; i++){
       for(j=1 ;j<10; j++){
           for(k=1 ;k<10; k++){
               for(l=1 ;l<10; l++){
                   // In this 4 if loops we will be checking for the 4 conditions given to find the
                   // Address of the riddler
                   if(i != j && j!=k && k!= l && l!= i){ // Check that the 4 digits are different
                   if(i == 3*k){ // Check the digit at thouisand place is 3 times the digit at tens place
                       if(l%2 != 0){ // Check the number is odd
                           if((i+j+k+l) == 27){ // Check the sum is equal to 27
                               System.out.println("The address where the Riddler plans to strike is " + i + j + k + l);                          
                               }
                           }
                       }
                       }
                   }
               }
           }
       }
   }
}
