It adds a second usage to the operator, just like you have had two uses of many of the operators above, such as adding two `Simpy`s or a `Simpy` and a `float`. The big idea of the second usage of subscription notation is that if instead of giving an `int` inside the subscription brackets you give a `list[bool]`, the expression will return a new `Simpy` object containing only the _masked_, or filtered, `values`. For example: ~~~python a = Simpy([1.0, 2.0, 3.0, 4.0, 2.0, 1.0]) mask = a > 2.0 print(mask) # Output: [False, False, True, True, False, False] b = a[mask] print(b) # Output: Simpy([3.0, 4.0]) ~~~ The above example did not need to establish a separate variable named `mask`, it only did so to make it obvious what the `mask` values were. More conventionally, the above example would be written in a…Please fix this code: Make it look like the EXPECTED PICTURE ( the read is wrong)

- Add a foreach loop at the end of the main method to print all the list elements side by side, separated by single spaces. Include a brief description so the output shows that these are the list elements printed with the foreach loop.Please provide an explaation and comments and check image for formula . Write approxPI(), a static method using a simple formula to return an approximate value of π. The method has a single int parameter n, the number of terms used to calculate π, and returns a double value. The simple formula (see notation), is expressed as: Step 1: a simple loop (i=0; i<=n) for the summation (Σ), stored to the variable pSum, of the terms: (-1)i / (2i + 1)pSum = 1/1 + -1/3 + 1/5 + -1/7 + 1/9 + -1/11 + 1/13 … (up to, and include, number of terms: n) i=0 i=1 i=2 i=3 i=4 i=5 i=6 … i <= n Step 2: after the summation, multiple by 4 to obtain the final approximation, piApprox = (4 * pSum) Hint: use Math.pow(x,y) (xy) to calculate (-1)iExample calls to the method:displayln ( "n=1: " + approxPI(1) ); // 2.666666666666667displayln ( "n=10: " + approxPI(10) ); // 3.232315809405594displayln ( "n=50: " + approxPI(50) ); // 3.1611986129870506 Test: - test with values of n: 10, 100, 500, 100000Need help with the parts that say TODO in images , This may be needed scoresheet code below package edu.vtc.cis2271.yahtzee; import java.util.ArrayList;import java.util.HashSet;import java.util.List;import java.util.Set; public class Scoresheet{ private static final int SMALL_STRAIGHT_SCORE = 30;private static final int LARGE_STRAIGHT_SCORE = 40;private static final int FULL_HOUSE_SCORE = 25;private static final int YAHTZEE_SCORE = 50;private static final int TOP_HALF_BONUS = 35;private static final int TOP_HALF_BONUS_LEVEL = 63; @SuppressWarnings("javadoc")public enum Category {Ones,Twos,Threes,Fours,Fives,Sixes,SmallStraight,LargeStraight,ThreeOfKind,FourOfKind, FullHouse, Yahtzee,Chance} public Scoresheet(){_scores = new int[Category.values().length];_listeners = new ArrayList<>();for (int i = 0; i < _scores.length; i++)_scores[i] = -1;} public void addScoreSheetListener(ScoreSheetListener listener){_listeners.add(listener);} public void…
