How many squares are drawn if foo(0,0,5,1) is called? Assume that the function drawSquare(double x, double y, double halfLen) draws a square witha side length that is double of halfLen, centered at (x, y). For example, drawSquare(0,0,5) drawsa square centered at (0,0) with each side of length 10.Consider the following function foo defined as:public static void foo(double x, double y, double len, int n) {if (n < 1) return;drawSquare (x, y, len);foo(x-len/2, y-len/2, len/2,n-1);foo(x-len/2, y+len/2, len/2,n-1);foo(x+len/2, y+len/2, len/2,n-1);foo(x+len/2, y-len/2, len/2,n-1);}

Holi is celebrated in India as a festival of colours and your friend Khan from India has gifted you X packets of colours. Now you are planning to make a beautiful rangoli, to make it you need to map all colours pairwise distinct, so that they look attractive. To do so, you can mix the colours zero or more times: o Pick any two random colours. Let's denote their weight by t and u. o Mix the colour with second colour. After the process, the value of the first colour remains t, but the weight of the second colour changes to t + u. Now you have to develop a python code to find the minimum number of mixing operations you needs to perform to make a beautiful Rangoli. Sample Test Case Scenario: 1 4 5324 Output:

Start with a pile of n stones and successively split a pile into two smaller piles until each pile has only one Each time a split happens, multiply the number of stones in each of the two smaller piles. (For example, if a pile has 15 stones and you split it into a pile of 7 and another pile of 8 stones, multiply 7 and 8.) The goal of this problem is to show that no matter how the pile of n stones are split, the sum of the products computed at each split is equal to n(n - 1)/2. Using strong mathematical induction, prove that no matter how the pile of n stones are split, the sum of the products computed at each split is equal to n(n - 1)/2.
Question: Update Bresenham’s line (JAVA) method such that you can scale the line before drawing it. Normally, you pass two points and a Graphics’ object to draw line using Bresenham’s algorithm. Now you’ll add scaling factors in arguments for scaling as shown below. public void drawBresenhamLine(Point p1, Point p2, double Sx, double Sy, Graphics g) { //Write your code here } Note: If you use scaling method, then also write Scale method in solution.
