T interval between time samples •n. number of time samples These variables have already been defined for you in the solution template. Follow the steps below to complete the script A. Start by calculating the final time sample value and assign the result to the variable tf That is, what will the final time value be if you want a vector of n time beginning at 0 and separated by a spacing of T? 2 Use the colon operator () to create row vector of n time samples trom e to tf spaced by T, and assign the result to the variable t. 3 Use t and the sin function to create the corresponding row vector of n sine function values evaluated at the fime values in t, where the amplitude, frequency, a the sine wave are given by the vanables above.

Complete the rotate_text() function that takes 2 parameters, a string data and an integer n. If n is positive, then the function will shift all the characters in data forward by n positions, with characters at the end of the string being moved to the start of the string. If n is 0 then the text remains the same. For example: rotate_text('abcde', rotate_text('abcde', rotate_text('abcde', 1) would return the string 'eabcd' 3) would return the string 'cdeab' 5) would return the string 'abcde' rotate_text('abcde', 6) would return the string 'eabcd' ... and so on. If n is negative, then the function will shift the characters in data backward by n positions, with characters at the start of the string being moved to the end of the string. For example: rotate text('abcde', -1) would return the string 'bcdea'

how would i make a javascript function as follows myChoice( items ) This function accepts a list of items as input and creates a function that returns a randomly-chosen item. After choosing a random item, that same item will be always be returned, regardless of the functions input, with one exception. If the first input is the string 'rechoose', then a new random item will be chosen and therafter returned. Examples var a = myChoice( [1, "a", 3, false] ); a( 3, 12 ) => 3 // a random value. Your code may differ. a( 51, -2) => 3 a( "happy", false ) => 3 a( [1,2,3]) => 3 a( 'rechoose') => false // a random value. Your code may differ. a( a, a ) => false
Integers are read from input and stored into a vector until 0 is read. If the vector's last element is odd, output the odd elements in the vector. Otherwise, output the even elements in the vector. End each number with a newline. Ex: If the input is -9 12 -6 1 0, the vector's last element is 1. Thus, the output is: -9 1 Note: (x % 2 != 0) returns true if x is odd. int value; int i; bool isodd; 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 } cin >> value; while (value != 0) { } for (i = 0; i > value; Check return 0; 1 Next level 2 X 1: Compare output 3 4 For input -9 12 -6 1 0, the vector elements are -9, 12, -6, and 1. The last element, 1, is odd. The odd elements in the vector, -9 and 1, are output, each on a new line. Not all tests passed. 2 V 3

Presentation exercise 2 Write a function (including docstring) called multiply_term that takes a polynomial as inputs and a term. We can represent polynomials as a collection or power-coefficient pairs. Consider the following polynomial: p(x) = 2 - a4 – 3. x+ 5. We can represent it as the following collection of pairs: (4, 2), (1, -3), (0, 5). We can represent a term as a tuple where the first value indicated the exponent in the term, and the second its coefficient. For example, the term 5 - a* is represented by the tuple (4, 5). The function does not return anything, but after its execution the input dictionary will now represent the multiplication of the input polynomial by the specified term. For example: Page 2 >> p = {2 : 1, 1 : 2} # x^2 + 2x >>> t = (4, 5) # 5x^4 >>> multiply_term(p, t) >>> p == {6 : 5, 5 10} True You can assume that the function will receive as input a dictionary mapping integers to numbers. No need for you to implement any type of input validation.
] ] get_nhbr In the cell below, you are to write a function called "get_nhbr(Ist, graph)" that takes in two inputs: a list of vertices and a graph. The function is to return a list that contains the neighborhood of the vertices in 'Ist' (remember that this means you are finding the union of the individual vertices' neighborhoods). + Code + Markdown After compiling the above cell, you should be able to compile the following cell and obtain the desired outputs. print (get_nhbr(["A", "D"], {"A" : ["B"], "B" : ["A", "D", "E"], "C" : ["E"], "D":["B"], "E":["B","C","F"], "F":["E"]}), get_nhbr(["B", "C", "F"], {"A" : ["B"], "B" : ["A", "D", "E"], "C" : ["E"], "D":["B"], "E":["B","C","F"], "F":["E"]})) This should return ["B"] ["A", "D", "E"] Python Python

Create the following functions makeBoard Accepts two parameters, integers mm and nn, and creates an mm x nn numpy array of zeros Returns the created array makeMove Accepts two parameters, a 2D array (such as created by makeBoard), and an integer xx Checks if the value at position xx in the array is 0. If it is, changes it to 1 and returns True If it isn't, does not change it and returns False Position xx in the array is given by reading the array top-down and left-to right. A simple 2x3 array is seen below with each value representing its position You may assume without checking that the value of xx provided is valid, that is it is within the array. Hint: Arrays have a property you can use to determine their shape. Hint: This function may (and indeed should) contain if statements, but no loops. Sample array with positions: [[0 1 2][ 3 4 5]] For testing purposes, you may copy the function provided here into your code def playGame(mm,nn): board = makeBoard(mm,nn)…
