Call your class BigFraction.java and implement it according to this specification. You will note that BigFraction is composed of BigInteger numerator and BigInteger denominator. Like BigInteger and BigDecimal, BigFraction is immutable. Also, take care to simplify all fractions during construction using the BigInteger gcd method and dividing both numerator and denominator by their greatest common divisor, noting that BigInteger has its own given gcd method. In our specification, the denominator is always positive; only the numerator can be either positive or negative. For a refresher on fraction arithmetic, see here. Field Detail ONE public static final BigFraction ONE ZERO public static final BigFraction ZERO Constructor Detail BigFraction public BigFraction(java.math.BigInteger numerator, java.math.BigInteger denominator) Given a BigInteger numerator and denominator, simplify the fraction by dividing both numerator and denominator by their greatest common…

There are three main operations on rectangles: intersection, union, and difference. Among them, only intersection is guaranteed to return another rectangle. In general, the union of two rectangles is... two rectangles, and the difference between two rectangles is ... a whole lot of rectangles, as we will see. We let you implement rectangle intersection. Of course, the intersection is defined only if the rectangles have the same number of dimensions. The intersection is computed by taking the intersection of the intervals of the two rectangles for corresponding dimensions. If one of the intervals is empty, you should return None. [] # @ title Rectangle intersection def rectangle_and(self, other): if self.ndims != other.ndims: raise TypeError("The rectangles have different dimensions: {} and {}".format( )) self.ndims, other.ndims ### YOUR SOLUTION HERE Rectangle. _and_ = rectangle_and [ ] r1 = Rectangle((2, 3), (0, 4)) r2 = Rectangle((0, 4), (1, 3)) draw rectangles (r1, r2) draw…
To perform a series of computational experiments, create a data type PercolationStats with the following API: public class PercolationStats { // perform independent trials on an n-by-n grid public PercolationStats(int n, int trials) // sample mean of percolation threshold public double mean() // sample standard deviation of percolation threshold public double stddev() // low endpoint of 95% confidence interval public double confidenceLow() // high endpoint of 95% confidence interval public double confidenceHigh() // test client (see below) public static void main(String[] args) } The constructor takes two arguments n and T, and perform T independent computational experiments (discussed above) on an n-by-n grid. Using this experimental data, it calculates the mean, standard deviation, and the 95% confidence interval for the percolation threshold. Standard libraries. Use stdRandom to generate random numbers; use stdStats to compute the sample mean and standard deviation; use stopwatch to…
