Why is a circular array implementation not as attractive as an implementation of a list as it was for a queue?

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 ""; } }

Write a program that will askthe user to enter the amount of a purchase. the program should thencompute the state and county sales tax. assume the state sales tax is4 percent and the county sales tax is 2 percent. the program should displaythe amount of the purchase, the state tax, the county sales tax, the total salestax, and the total of the sale. (which is the sum of theamount of purchase plus the total sales tax). hint: use the value 0.02 torepresent 2 percent, and 0.04 to represent 4 percent.
