Using K-maps, extract the most simplified SOP function for 4-digits binary 2’complementer. The binary function will have 4 inputs and 4 outputs, (e. g. if the input is 0001 the output must be

1111).

a)The inputs ranges from 0000-1111, and you may use A B C D as input digits and S1 S2 S3 S4 as

output digits.

A B C D | S1 S2 S3 S4

0 0 0 0 | 0 0 0 0

0 0 0 1 | 1 1 1 1

………….

1 1 1 1 | 0 0 0 1

b) Draw the circuit. The circuit is a simplified two-level circuit, plus inverters as needed for the

input variables.

This problem has been solved! see the answeran evil king has a cellar containing n bottles of expensive wine, and his guards have just caught a spy trying to poison the king’s wine. fortunately, the guards caught the spy after he succeeded in poisoning only one bottle. unfortunately, they don’t know which one. to make matters worse, the poison the spy used was very deadly; just one drop diluted even a billion to one will still kill someone. even so, the poison works slowly; it takes a full month for the person to die. design a scheme that allows the evil king to determine exactly which one of his wine bottles was poisoned in just one month’s time while expending at most o(logn) of his taste testers.you are not allowed to use n testers, one for each bottle, and see which one tester dies after 30 days.(no pseudocode needed. just answer in words, how many testers you use, how you use them and why you correctly identify the poisoned bottle in 30 days)

Design a class tictactoe that: holds the following information about the game: two-dimensional array (3 by 3), and winner. add additional variables as needed. includes the functions to perform the various operations on objects. for example, function to print the board, getting the move, checking if move is valid, determining if there is a winner after each move. add additional operations as needed. includes constructor(s). write the functions of the class, and write a program that uses the class. the program should declare an object of type tictactoe. the program will create the board and store it in the array. the program will allow two players to play the tic-tac-toe game. after every valid move update the array, check if there is a winner. if there is no winner and no tie, then print the board again to continue.
