Consider a system that uses a 32-bit unique salt where users have a 4-digit number as a password (e. g. 6813). Eve wants to crack the accounts of two users, Alice and Bob. Eve performs an online attack, and is able to guess 1 password per second, though there is no lockout after guessing too many times. In the worst case, in seconds, how long will it take Eve to crack both Alice's and Bob's accounts?

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 ""; } }
