Decide whether the function is one-to-one. If the function is one to one find two elements that have the same image
f : set of ten students ® {A, B, C, D, F}
f(student) = one letter grade
Step by step
Solved in 2 steps with 2 images
- Decide whether the following functions are one to one. If the function is not one to one find two elements which have the same image. c) f : set of ten students ® {A, B, C, D, F} f(student) = one letter grade d) f : R ® R f(x) = x2 - 122. What does the function all () do? Returns 1 if all elements within it are 0 Returns 0 if all elements within it are non-zero Returns 0 if all elements within it are 0 Returns 1 if all elements within it are non-zeroCyclops numbersdef is_cyclops(n):A nonnegative integer is said to be a cyclops number if it consists of an odd number of digits so that the middle (more poetically, the “eye”) digit is a zero, and all other digits of that number are nonzero. This function should determine whether its parameter integer n is a cyclops number, and return either True or False accordingly n Expected result 0 True 101 True 98053 True 777888999 False 1056 False 675409820 False
- 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') .Assignment 5C: Level Map Creator. There are a variety of ways that game developers store their level layouts. One simple method is to associate level elements with certain symbols, and then storing them in a 2D grid inside a text file. We will use our knowledge of 2D arrays to create a very simple Level Map Creator tool. The program should prompt the user to enter a width and height for the level. Then it should initialize a 2D array and fill every element with the *" symbol. Afterwards, the user should be given the following options via a menu: 1. Clear Level 2. Add Platform Prompt the user to enter a starting point and length for the Re-initialize the 2D array and fill every element with the "** symbol. horizontal platform. Replace those elements in the 2D array with the "=" symbol. If the length is longer than the number of columns |(or out of bounds), notify the user that this is not possible. Prompt the user to enter a column and row index. Replace that element in the 2D array…In C programming language Question (Strings) Write a function find_Substring() that finds a substring into a string.

- Each of two players rolls a dice and whoever rolls the highest number (between 1 and 6 inclusive) gets 4 points, and if it is a draw, both players get 2 points. The player with the highest number of points after 10 rounds of the game is the winner (or the game could be drawn). The following arrays contain the results of dice rolls of each of two players in 10 consecutive rounds of the game.player1=[3, 2, 5, 6, 2, 5, 1, 6, 4, 5]player2=[4, 2, 4, 3, 6, 5, 3, 2, 4, 1] Write a MATLAB program that computes the running total points of each player and displays one of the following messages (whichever applies) after each round n for n = 1, 2, . . . , 10:Player 1 is leadingPlayer 2 is leadingIt is a tie [Hint: You should use an if construct.]Also, at the end of your program, use the find command to identify (and display) the rounds in which dice rolls were the same for the two players, and use the length command to compute (and display) the number of such rounds. Include appropriate headings in…What is the result of this function Len("collage") * 7 col O collage ageIf a two dimensional array is used as a formal parameter, then A. both the subscripts may be left empty B. the first (row) subscript may be left empty C. the first subscript must be left empty D. both the subscripts must be left empty
- javascript Define a function, myIncludes, that accepts two parameters: an array and a searchValue. myIncludes should return true if the searchValue is an element in the array. Otherwise, myIncludes should return false. example myIncludes([10, 20, 30], 20); // => true myIncludes(['apples', 'bananas', 'citrus'], 'pears'); // => falseGrades 0-100 will be assigned randomly in a series with 30 elements. Taking their averages (shown on the screen), those above the average will be divided into an array and the ones below will be divided into an array by the function named "plenty" (two different sequences will be obtained). (Pointer is required.)Then, with the function named "gor", the grades of the whole class, those above the average, those below the average will be displayed on the screen.Write the C program code that performs the above operations.Dart game: Dart location Write a function called DartNumbers() that takes the location of darts thrown as an input, and finds the number of darts that hit the regions yellow, red, blue, and green. 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. Dart Board 10 2. -2 -10 -10 -2 4. 8. 10 The inputs of the function DartNumbers() are: throwX: Indicates the x positions of the darts on the board. throwX is a 1x10 array of random numbers between -10 and 10 with a uniform distribution using the rand function. throw Y:…
