Analyze the following code:
public class test {
public static void main(string[] args) {
b b = new b();
b. m(5);
system. out. println("i is " + b. i);
}
}

class a {
int i;

public void m(int i) {
this. i = i;
}
}

class b extends a {
public void m(string s) {
}
}
a. the program has a compile error, because m is overridden with a different signature in b.
b. the program has a compile error, because b. m(5) cannot be invoked since the method m(int) is hidden in b.
c. the program has a runtime error on b. i, because i is not accessible from b.
d. the method m is not overridden in b. b inherits the method m from a and defines an overloaded method m in b.

You need to design a circuit that implements the functions in the following table: s0 s1 function0 0 a + 10 1 a – b1 0 a + b1 1 a – 1s0 and s1 are 1-bit control inputs to select the function of the circuit. inputs a and b are 4-bitnumbers in 2s complement form. the output is also a 4-bit number in 2s complement form. you are allowed to use only one ttl 7483 4-bit adder to implement all the functions. but anynumber of other components (except the adder) can be used. hint: design a combinational logic circuit to modify the input b and the “carry input” of theadder depending on the control inputs s0 and s1.important: lab grade will depend on the working of the circuit & will be checked of by your labinstructor.1. is the output valid for the following input combinations: a. s0 = 0, s1 = 0, a = 7, b = 3? b. s0 = 0, s1 = 1, a = 7, b = 3? c. s0 = 1, s1 = 0, a = -4, b = -5? d. s0 = 1, s1 = 1, a = -8, b = 6? 2. what is the range of inputs (for both a and b) that will produce the valid output for all the functions?

Why were most movies from the late 1890s until the early 1930s only filmed in black and white? there were only a few people who could afford the technology to produce color motion pictures back then. audiences did not want color motion pictures until later. the film used to make color motion pictures often overheated, which was a safety hazard, so it was generally not allowed. color films had to be hand-colored, frame by frame.
