Request one four-digit number, such that each digit is different. without requesting another number, create a new number with the first and last digits of the previous number swapped. subtract the smaller number from the larger and add together the digits of the resulting number, then add the two digits together (if the sum is only one digit, zero can be added).

Acommon algorithm for converting a decimal number to binary is to repeatedly divide the decimal number by 2 and save the remainder. this division is continued until the result is zero. then, each of the remainders that have been saved are used to construct the binary number. write a recursive java method that implements this algorithm. it will accept a value of int and return a string with the appropriate binary character representation of the decimal number. my code: public class lab16{public string converttobinary(int input){int a; if(input > 0){a = input % 2; return (converttobinary(input / 2) + "" +a); } return ""; } }
