- The text presented the Sierpinski triangle fractal. Inthis exercise, you will write a program to display another fractal, called the Kochsnowflake, named after a famous Swedish mathematician. A Koch snowflake iscreated as follows:1. Begin with an equilateral triangle, which is considered to be the Koch fractalof order (or level) 0, as shown in Figure a.2. Divide each line in the shape into three equal line segments and draw an outwardequilateral triangle with the middle line segment as the base to create aKoch fractal of order 1, as shown in Figure b.3. Repeat Step 2 to create a Koch fractal of order 2, 3, . . . , and so on, as shownin Figures c and d.The code is below and use the code to answer the 3 questions that is attached as an image: #include <stdio.h>#include <stdlib.h>#include <unistd.h>#include <errno.h>#include <signal.h> void sigint_handler(int sig){ (void)sig; // remove unused variable warning write(0, "Ahhh! SIGINT!\n", 14);} int main(void){ void sigint_handler(int sig); /* prototype */ char s[200]; struct sigaction sa; sa.sa_handler = sigint_handler; sa.sa_flags = 0; // or SA_RESTART; sigemptyset(&sa.sa_mask); // if (sigaction(SIGINT, &sa, NULL) == -1) {// perror("sigaction");// exit(1);// } printf("Enter a string:\n"); if (fgets(s, sizeof s, stdin) == NULL) perror("fgets"); else printf("You entered: %s\n", s); return 0;}Write a loop that subtracts 1 from each element in lowerScores. If the element was already 0 or negative, assign 0 to the element. Ex: lowerScores = {5, 0, 2, -3} becomes {4, 0, 1, 0}. #include <iostream>using namespace std; int main() { const int SCORES_SIZE = 4; int lowerScores[SCORES_SIZE]; int i; for (i = 0; i < SCORES_SIZE; ++i) { cin >> lowerScores[i]; } /* Your solution goes here */ for (i = 0; i < SCORES_SIZE; ++i) { cout << lowerScores[i] << " "; } cout << endl; return 0;}

- Dont display elements with coefficient=0sign "+" should be showned for coefficients bigger than 0, coefficients 1 & -1, if they are not constant terms, not showned, for -1 only "-" should be displayed, you can display "^" for marking powers of variable x, so polynomial should be showned W(x) = 2 x^4 - x^3 + x^2 -6.in certain case, when all coefficients/all coefficients except constant term are equal 0, you have to display only constant term, for example for array {-1, 0. 0, 0, 0} displayed polynomial is W(x)=-12. Create a function, which adds two polynomials (in the same power) and coefficients of received polynomial are saved in 3rd array.3.

On this hiking trail, there is elevation marker at every kilometer. The elevation information is represented in an array of integers. For example, if the elevation array is [100, 50, 20, 30, 50, 40], that means at kilometer 0, the elevation is 100 meters; at kilometer 1, the elevation is 50 meters; at kilometer 2, the elevation is 20 meters; at kilometer 3, the elevation is 30 meters; at kilometer 4, the elevation is 50 meters; at kilometer 5, the elevation is 40 meters. b) Write a method called longestUphill that returns the elevation change in meters of the longest uphill section. In the example above, the method should return 30 because the longest uphill section is from kilometer 2 with 20 meters to kilometer 4 with 50 meters. The elevation change is 50 - 20 = 30 meters. Note: A flat section with no elevation change is not considered part of an uphill.Draw a wall with "irregular wavy color bands". Hint: you can use curveVertex and random functions in p5js library. Note: You should use loops to draw the lines, not manually write 50-100 line functions How would i answer this question using the code below: function setup() { createCanvas(350, 350); } function draw() { background(200); background('blue'); noFill(); //this will run a loop form -20 to fill the whole canvas for(let y=-20; y<300; y+=4){ beginShape(); Stroke("yelllow"); //now to link point to point in curve //y is height curveVertex(0, y+0); curveVertex(0, y+20); curveVertex(50, y+0); curveVertex(100, y+20); curveVertex(150, y+0); curveVertex(200, y+20); curveVertex(250, y+0); curveVertex(300, y+20); curveVertex(350, y+0); curveVertex(400, y+0); endShape(); } } Subject: Java Programming
