I NEED ANSWER ASAP PLEASE!!!!

i meed answer asap!! task 0 and 1 are questions.

Task 0- (1 Var mux): Implement the functionality of a 1 var multiplexer. A 1 var multiplexer has 1 selector line, 2 input lines, and 1 output line. The selector line determines which input will be sent to the output. Because a bit can be either 0 or 1 , that means that a selector line can choose between two inputs. Selector line: so 0 would stand for the first input(i0) 1 would stand for the second input(i1) Task 1- (2 Var mux): Implement the functionality of a 2 var multiplexer. A 2 var multiplexer has 2 selector lines, 4 input lines, and 1 output line. The selector line determines which input will be sent to the output. Because a bit can be either 0 or 1 , that means that a selector line can choose between two inputs. When there are two selector lines, it can choose one input out of four possible inputs to send to the output line. \#include \#include \#include I/ BEGIN STRINGBUILDER IMPLEMENTATION I/ Don't edit the stringbuilder implementation. /I This code is a very rudimentary stringbuilder-like implementation II To create a new stringbuilder, use the following line of code II II stringbuilder sb=newSsb(); II II If you want to append a character to the stringbuilder, use the II following line of code.
