• int getNumAccidents () is passed the name of a region. It asks the user for the number of automobile accidents reported in that region during the last year, validates the input, then returns it. It should be called once for each city region.
• void findLowest () is passed the five accident totals. It determines which is the smallest and prints the name of the region, along with its accident figure.
Input Validation: Do not accept an accident number that is less than 0.

- Lowest Score Drop Write a program that calculates the average of a group of test scores, where the lowest score in the group is dropped. It should use the following functions: void getScore() should ask the user for a test score, store it in a reference parameter variable, and validate it. This function should be called by main once for each of the five scores to be entered. void calcAverage() should calculate and display the average of the four highest scores. This function should be called just once by main and should be passed the five scores. int findLowest() should find and return the lowest of the five scores passed to it. It should be called by calcAverage, which uses the function to determine which of the five scores to drop. Input Validation: Do not accept test scores lower than 0 or higher than 100.arrow_forwardTreasure Hunter description You are in front of a cave that has treasures. The cave canrepresented in a grid which has rows numbered from 1to , and of the columns numbered from 1 to . For this problem, define (?, )is the tile that is in the -th row and -column.There is a character in each tile, which indicates the type of that tile.Tiles can be floors, walls, or treasures that are sequentially representedwith the characters '.' (period), '#' (hashmark), and '*' (asterisk). You can passfloor and treasure tiles, but can't get past wall tiles.Initially, you are in a tile (??, ). You want to visit all the treasure squares, andtake the treasure. If you visit the treasure chest, then treasurewill be instantly taken, then the tile turns into a floor.In a move, if you are in a tile (?, ), then you can move tosquares immediately above (? 1, ), right (?, + 1), bottom (? + 1, ), and left (?, 1) of thecurrent plot. The tile you visit must not be off the grid, and must not be awall patch.Determine…arrow_forwardPhython: Create a function so that when giving you a month it tells you the season of that month, for example: if it is January it will be winter.Using the def, try and except ValueError functions.arrow_forward
- Python question Application: Python Fragment Formulation (Q1 – Q4) In this group of questions you are asked to produce short pieces of Python code. When you are asked to "write a Python expression" to complete a task, you can either give the expression in one line or break down the task into several lines. The last expression you write must represent the required task. Question 1 (Reduce parentheses) Give an equivalent version of this expression by removing as many redundant parentheses as possible, without expanding the brackets or simplifying. (x**(2**y))+(y*((z+x)**3)) Question 2 (Translate arithmetic concept into Python) You are given a list of numbers, named numbers, containing 3 integers. Write a python expression (one line) that evaluates to True if and only if the product of any two numbers in the given list is greater than the sum of all three numbers. Note: the product of two numbers, x and y is x*y. Question 3 (List/table access) You are given a table,…arrow_forwardUsing the starter code below, write a program that asks a user for two points (x1, y1) and (x2, y2), then computes the area of the circle for which (x1, y1) is the center and (x2, y2) is on the circle's perimeter. The program should define and use 3 functions: distance(x1, y1, x2, y2): computes and returns the distance between two points • area(r): computes and returns the area of a circle with radius r • main(): asks user for input, calls the other functions, and prints the answer. The input and output of the program should look similar to this: X for center point: 0 Y for center point: 0 X for perimeter point: 1 Y for perimeter point: 1 Area of circle centered at (0.0, 0.0) with radius 1.414213 is 6.283185. Hint 1: Area of a circle = n? Hint2: Distance between 2 points = sqrt(x2-X12 + (Y2 - Y1)²) Starter code: import math def distance(x1, y1, x2, y2): #Add code to compute and return distance between (x1, y1) and (x2, y2) def area(r): #Add code to compute and return area of circle…arrow_forwardExercise 2: Hospital Patients Write a program that computes and displays the charges for a patient’s hospital stay. First, the program should ask if the patient was admitted as an inpatient or an outpatient. If the patient was an inpatient, the following data should be entered: The number of days spent in the hospital The daily rate Hospital medication charges Charges for hospital services (lab tests, etc.) The program should ask for the following data if the patient was an outpatient: Charges for hospital services (lab tests, etc.) Hospital medication charges The program should use two overloaded functions to calculate the total charges. One of the functions should accept arguments for the inpatient data, while the other function accepts arguments for outpatient information. Both functions should return the total charges and display it for the user. After the total charges have been calculated and displayed, write the result to a file,…arrow_forward

A 20x20 square dart board, as shown in the image below, consists of concentric circles with the center at (0,0). The radius of the yellow circle is 3, the red circle is 5, and the blue circle is 10. A dart player throws 10 darts at the board randomly such that any place on the board can be hit with an equal chance. The rand() function can be used to obtain a number with uniform distribution between -10 and 10. Uniform distribution with a given interval means that an equal probability exists to get a number in that interval.

The validation process for these magical codes involves a combination of mathematical spells. The validation process is described as follows: Take the sum of the digits at odd positions from left to right. Take the sum of the squared digits at even positions from left to right. If the absolute difference between the results from step 1 and step 2 is a prime number, the book code is considered valid; otherwise, it is invalid. Example 1: Consider the magical book code 86420137. Step 1. Take the sum of the digits at odd positions from left to right. 8+4+0+3=15 Step 2. Take the sum of the squared digits at even positions from left to right. 6^2+2^2+1^2+7^2=36+4+1+49 = 90 Step 3. If the absolute difference between the results from step 1 and step 2 is a prime number. 115-901 75 (not a prime number) Book code 86420137 is invalid. Example 2: Now, let's examine the…arrow_forward
