What you need to Implement? Your task is to implement two versions of the example reducer from MDN, so that these new functions can handle non-numeric values in the array in a graceful manner. Here are the 2 functions you need to implement: reducer1 If this function is passed to reduce, any non-numeric values in the array will be skipped and the sum of only the numeric values in the array will be returned. o If all the values in the array are non-numeric, then the value O will be returned. reducer2 If this function is passed to reduce and the array contains any non-numeric values, this function will throw the exception TypeError. • Otherwise, the sum of all the values in the array will be returned. • To throw the exception TypeError with the message 'My error message' you can use the statement throw new TypeError('My error message'). See TypeError on MDN for more discussion of this exception.

Now, write another function that prints the values of any array in reverse order. (The function should not change the original array). As an example, if a [] = {1, 2, 3, 4, 5}; The function would print the values in reverse as: 5, 4, 3, 2, 1

What is the big O notation for this function?

In this assignment, you will decide how to keep the inventory in the text file. Then your program must read the inventory from the file into the array. Each product must have a record in the file with the name, regular price, and type. There are several options for storing records in the file. For example, • each value takes one line in the file (i.e., three lines for one product). Then you must take care of correct handling of the ends of the lines; • all values are in one line that can be read as a string. Then you must handle the parsing of the string; • all values are in one line separated by a delimiter. Then you must handle a line with delimiters. Assume that the inventory does not have more than 100 products. But the actual number is known only after the reading of the file. Once you can read data from the file into the array, you must add a new property to the product class – a static variable that holds the number of products in the inventory. Its value must grow as reading…

In cell C18 type a VLOOKUP function to find the corresponding letter grade (from column D) for the name in A18. The table array parameter is the same as in B18. Type FALSE for the range lookup parameter. Copy the formula in C18 to C19:C22Notice this formula works correctly for all cells. Range lookup of FALSE means do an exact match on the lookup value whether or not the table array is sorted by its first column. In cell E11, type an IF function that compares the score in B11 with the minimum score to pass in A5. If the comparison value is true, display Pass. Otherwise, display Fail. Copy the formula in E11 to E12:E15. Did you use appropriate absolute and relative references so the formula copied properly? In cell F11, type an IF function that compares the grade in D11 with the letter F (type F). If these two are not equal, display Pass. Otherwise, display Fail. Copy the formula in F11 to F12:F15

What transpires when a parameter for an array is sent in with either the ref or out keyword, and the results are observed?

python only define the following function: This function must reset the value of every task in a checklist to False.  It accept just one parameter: the checklist object to reset, and it must return the (now modified) checklist object that it was given. Define resetChecklist with 1 parameter Use def to define resetChecklist with 1 parameter   Use a return statement Within the definition of resetChecklist with 1 parameter, use return _in at least one place.   Use any kind of loop Within the definition of resetChecklist with 1 parameter, use any kind of loop in at least one place.

You are designing a function that will manipulate an array of integers. It needs to work for arrays of any length. What is the minimum number of parameters your function will have?

DESIGN YOUR OWN SETTING Task: 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, include the following to your answer: 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
