Developers often think of software quality in terms of faults and failures. Faults are problems (for example, loops that never t

erminate or misplaced commas in statements) that developers can see by looking at the code. Failures are problems, such as a system crash or the invocation of the wrong function, that are visible to the user. Thus, faults can exist in programs but never become failures, because the conditions under which a fault becomes a failure are never reached. How do software vulnerabilities fit into this scheme of faults and failures? Is every fault a vulnerability? Is every vulnerability a fault?

While developing application solutions, software developers are always advised to consider producing secure code that is not vulnerable to hacks. Vulnerabilities, in the simplest of terms, can be described as an error or a fault in code. These errors or bugs, as a result, can cause unexpected actions like system crashes or connectivity issues. Some can go as far as creating information leakage and allowing unauthorized system access. Therefore, it is almost always certain that some bugs will cause vulnerabilities on software that have those bugs in them. It is also fit to say that faults in software are part of a larger list of factors that can cause software vulnerabilities. However, note that not all vulnerabilities are faults.

we are given an array a consisting of n distinct integers. we would like to sort array A into ascending order using a simple alg
marta [7]

Answer:

Check the explanation

Explanation:

the js code is as follows

function count_max_group(ar) {

if (ar.length < 2) return ar.length; // if no of elements are 2 then max groups are 2

let st = [0]; // stack to store the groups

for (let i = 1; i < ar.length; i++) {

if (ar[i] >= ar[i - 1]) st.push(i); // pushing elements if if ar[i] is greater than the previous element

for (let j = i; j > 0 && ar[j] < ar[j - 1]; j--) { // finding the max number of grps

swap(ar, j, j - 1); // swapping

if (j <= st[st.length - 1]) st.pop();

}

}

return st.length;

}

function swap(a, i, j) { // function to swap two variables

let t = a[i];

a[i] = a[j];

a[j] = t;

}

//sample solutions

console.log("the sample solutions are\n");

console.log("[2,1,6,4,3,7]\n");

(PYTHON HOMEWORK)Given the following code snippet, which statement tests to see if all three sets are equal?:
wariber [46]

Answer:

Option D is the correct answer to the following question.

Explanation:

The following option is correct because three sets type variable i.e., "fruit", "fruit2", "fruit3" has contain the same values in it and then they ask for the option is correct if the all are equal and in the option c, there is the if statement in which check the condition if the variable "fruit" is equal to the variable "fruit2" and the variable "fruit" is equal to the variable "fruit3".

so, that' why the following option is correct.

The option A is not correct because there is no equal function in python and we use the operator == to check the condition.

The option B is incorrect because we can see that there is not equal to (!=) operator.

The option D is incorrect because we can see that there is an or operator are used which means if any of the conditions is true then, they return either the other condition is false.

Answer:

see explaination

Explanation:

Part 1:

import java.util.Scanner;

Scanner scnr = new Scanner(System.in);

int num1;

int num2;

int num3;

int num4;

int avg=0, pro=1;

num1 = scnr.nextInt();

num2 = scnr.nextInt();

num3 = scnr.nextInt();

num4 = scnr.nextInt();

avg = (num1+num2+num3+num4)/4;

pro = num1*num2*num3*num4;

System.out.println(pro+" "+avg);

}

}

------------------------------------------------------------------

Part 2:

import java.util.Scanner;

public class LabProgram {

public static void main(String[] args) {

Scanner scnr = new Scanner(System.in);

int num1;

int num2;

int num3;

int num4;

double avg=0, pro=1; //using double to store floating point numbers.

num1 = scnr.nextInt();

num2 = scnr.nextInt();

num3 = scnr.nextInt();

num4 = scnr.nextInt();

avg = (num1+num2+num3+num4)/4.0; //if avg is declared as a float, then use 4.0f

pro = num1*num2*num3*num4;

System.out.println((int)pro+" "+(int)avg); //using type conversion only integer part

System.out.printf("%.3f %.3f\n",pro,avg);// \n is for newline

}
