Programming & Computer Science Answers

Assume we have TINGEN, a multi-core mobile processor. As writing an application in assembly language for the certain device, we have two selections concerning code optimization.

Option A: Do essential optimization steps before and then write the code.

Option B: First code the program in a normal way and then make necessary changes in order to optimize it.

Can we prefer any approach over the other or both are acceptable?
Kindly help in solving this question.

Write a Javascript function that creates an array of the months of the year, accepts a range of numbers (31 - 42) and alerts the corresponding month of the year in the array.

(1) Define a function maxOfThree() that takes three numbers as arguments and returns the largest of them.

(2)Define a function reverse() that computes the reversal of a string. For example, reverse("jag testar") should return the string "ratset gaj".

(3)Write a function filterLongWords() that takes an array of words and an integer i and returns the array of words that are longer than i.

(4)Write a function charFreq() that takes a string and builds a frequency listing of the characters contained in it. Represent the frequency listing as a Javascript object. Try it with something like charFreq("abbabcbdbabdbdbabababcbcbab"). Define a Javascript function that encapsulates the above functions.
note:all those program are in javascript.

thanks and God bless you
