- User-defined ordinal data types: pros and cons? Associative arrays have pros and cons, which are discussed below.When working with ordinal data, user-defined ordinal types come in handy. There are several advantages and cons of using an associative array.PHP Write a reduce function Write a function reduce($arr, $func) that takes an array and a function as a parameter. The reduce function should apply the parameter function to each element of the array in succession to produce a single result. Note: the current result should always be the first parameter to the function and the next element of the array should always be the second parameter. You may not use the PHP function array_reduce in your solution. For example, the result of the following should be 10. function myMax($current, $new) { return $current < $new ? $new : $current; } $arr = array(10, 5, 3, 5, 1, 2, 5, 7, 4); print("Max: " . reduce($arr, 'myMax') .
- User-defined ordinal types are beneficial when working with ordinal data. An associative array possesses many benefits and disadvantages.The Problem: Matching Group Schedules The group schedule matching takes two or more arrays as input. The arrays represent slots that are already booked and the login/logout time of group members. It outputs an array containing intervals of time when all members are available for a meeting for a minimum duration expected. Sample Input Enter person1_Schedule =[[ ‘7:00’, ’8:30’], [’12:00’, ’13:00’], [’16:00’, ’18:00’]] person1_DailyAct = [‘9:00’, ’19:00’] Enter person2_Schedule = [[ ‘9:00’, ’10:30’], [’12:20’, ’13:30’], [’14:00’, ’15:00’], [’16:00’, ’17:00’ ]] person2_DailyAct = [‘9:00’, ’18: 30’] Enter duration_of_meeting =30 Sample output [[’10:30’, ’12:00’], [’15:00’, ’16:00’], [’18:00’, ’18:30’]] Implementation Have following files Project1_starter.py or project1_starter.cpp that defines functions for the algorithm described above. You will need to develop and write the functions. Describe how to run your program in the ReadMe file Input.txt containing the sample input…Task 3: Statistics using arrays: by java programming With the spread of COVID 19, the HR department in a company has decided to conduct some statistics among the employees in order to determine the number of infections according to some conditions. For each employee, they have to record the code, name, age, whether he/she was infected or no and the remaining days of leaves for him/her. You are requested to write the program that maintains the lists of details for the employees as mentioned above using the concept of arrays. The program repeats the display of a menu of services until the user decides to exit. 1. Start by initializing the employee details by reading them from the keyboard. 2. Repeat the display of a menu of 4 services, perform the required task according to the user’s choice and asks the user whether he/she wants to repeat or no. You need to choose one service from each category (‘A’,’B’,’C’,’D’) a. A. Display the total number of employees that were infected b. B.…
- 1. Display Function Implement a function to display the contents of the patient_list array. Add code to call this function. Note that there are multiple places where this function needs to be called. Look for the // TODO comments to find the correct locations. 2. Sorting the array by Age Implement the code to sort the contents of the patient_list array based on the value stored in the age field. To do this you will need to implement code that relies on the qsort function from the C Standard library A function that compares two patient elements, based on the value stored in the age field. A call to the qsort function, which includes the array to be sorted, the number of elements in the array, the size of each array element and the function used to compare the array elements. Add code to call the qsort function, using the age comparison function that you implemented. This code should be placed just under the appropriate // TODO comment in main(). Sorting the array by…____ is the process of examining the elements of an array in order, looking for a match for a specific value.Create a function that takes a number that represents a person's programming language score, and returns an alphabetised array of programming languages they are proficient in. Arbitrarily assigned points for each language are listed below: Language Points C# C++ Java PHP Python Ruby Swift 1 Examples 2 JavaScript 8 4 16 32 64 128 get Languages (25) getLanguages (100) getLanguages (53) ["C#", "JavaScript", "PHP"] ["Java", "Python", "Ruby"] ["C#", "Java", "PHP", "Python"]
- DESIGN YOUR OWN SETTING Task 5: Devise your own setting for storing and searching the data in an array of non-negative integers redundantly. You may just describe the setting without having to give an explicit algorithm to explain the process by which data is stored. You should explain how hardware failures can be detected in your method. Once you have described the setting, complete the following: Write a pseudocode function to describe an algorithm where the stored data can be searched for a value key: if the data is found, its location in the original array should be returned; -1 should be returned if the data is not found; -2 should be returned if there is a data storage error Include a short commentary explaining why your pseudocode works Describe the worst-case and best-case inputs to your search algorithm Derive the worst-case and best-case running times for the search algorithm Derive the Theta notation for the worst-case and best-case running times Maximum word…Arrays An array is a sequence of data items that are of the same type, that can be indexed, and that are stored contiguously. Typically, an array is called a data structure used to represent a large number of homogeneous values. The elements of an array are accessed by the use of subscripts. Subscripts start from zero and runs until less than the size of the array. Arrays of all types are possible, including multi-dimensional arrays. Strings are just arrays of characters terminated by a special character called the null character. A typical array declaration allocates memory starting from a base address. The array name is in effect a constant pointer to this memory address. a) Write a complete C program that demonstrates usage of a one-dimensional array of integers. The program should declare an array of a specific size first, and then should ask user to specify values to be stored to the array. The program should finally display all values from the array to the screen for checking if…C+++ proram An organization is going to design a small database to store the records of students. They hire you in the development team and assign a small module of the project. You have to store the firstName, LastName, address, sapId, semester, and CGPA of all the students in a class. You are supposed to use 2D character array to store firstName and lastName. To test the working of your module you can fix the class size to 15. Pass these arrays into a displayRecord function which display complete information of all the students in a class. Create a function updateRecord which receives the sapId and search that whether this sapId exist in the array. If it exists than change the firstName, address and CGPA of that student otherwise display a simple message that "record does not exist
