Efficiency Analysis. For each problem given below, do the following: 1. Create an algorithm in pseudocode to solve the problem. 2. Identify the factors that would influence the running time of your algorithm. For example, if your algorithm is to search an array the factor that influences the running time is the array size. Assign names (such as n) to each factor. 3. Count the operations performed by the algorithm. Express the count as a function of the factors you identified in Step 2. To do that, identify the basic operations of the algorithm. There is no need count every statement separately only the ones that will influence the running time. 4. Describe the best case scenario for the algorithm and derive the big O. 5. Describe the worst case scenario for the algorithm and derive the big 0. The problems are: 1. Determine if two arrays have no elements in common. 2. Counting the total number of characters that have a duplicate within a string, including spaces. (i. e. "gigi the gato" would result in 9 (g*3 + 1*2 + 1*2+" "*2) 3. Finding a row where every entry is 'x' in a 2-D array.

Ihave a music player on my phone. i can buy songs, add them to playlists and play them. obviously it would be redundant to store each song in each playlist; each playlist is just a list of pointers to the songs. for this lab you will simulate this behavior. your program will need to have options to: add songs to the system library (you will store the text of the first line of the song, rather than the audio) add playlists add songs to a playlist list playlists play a playlist list all of the songs in the library with a count of how many times each song has been played remove a song from a playlist remove a playlist remove a song from the library (and thus from all playlists that contain it) note that we will not be checking many error cases. in real programming this would be bad, you should usually try to recognize and respond to as many types of errors as you can. in the context of class we are trying to acquaint you with as many concepts as possible, so for the sake of educational efficiency we will not be checking most errors in this lab, you may assume that your user provides correct input. you may add all appropriate error testing if you wish, but we will not be testing for it.

Sally is editing her science report about living things. she needs to copy a paragraph from her original report. order the steps sally needs to do to copy the text to her new document.

Anul 2017 tocmai s-a încheiat, suntem trişti deoarece era număr prim, însă avem şi o veste bună, anul 2018 este produs de două numere prime, 2 şi 1009. dorel, un adevărat colecţionar de numere prime, şi-a pus întrebarea: “câte numere dintr-un interval [a, b] se pot scrie ca produs de două numere prime? “.
