Task is to generate a list of 100 random integers between 1 and 1000. The integers should be sorted from smallest to largest and have no duplicates.
Your code should perform at most n operations, where n = 100 in this case. What this means is that your random generation function random.randint(x,y) should not be called more than 100 times.
Why would you randomize a program by using srand? Under what circumstances is itdesirable not to randomize?

- Retrieving a value using its associated key can be accomplished using anindexer, which works just like an indexer for an array. A key is passed in asthe index value, and the value associated with the key is returned, unless thekey doesn’t exist, in which a null is returned.Write short code segment demonstrates how this technique works:arrow_forwardCan't we modify binary search to only display the result with book title with its ID number where the user will search a book using an ID?arrow_forwardWrite a Program to Implement Selection Sort.arrow_forward
- You are free to generate sequences by any method you like (i.e. any algorithm or just an intuition).arrow_forwardOn average, how long does a randomized quick sort take, and how much room does it require?arrow_forwardWrite a loop that accomplishes the reconstruction for the edit distance problem. It should start at the end (m,n) and work its way back to the beginning, writing down the basic edit operations to use. That will write the operations backwards.arrow_forward
- When doing searches using EXCEPT (MINUS), does the order in which the operands are entered make a difference?arrow_forwardHere is the iterative implementation of binary search: For each call to binary_search below, indicate how many times the code inside the while loop will execute. animals = ["aardvark", "cat", "dog", "elephant", "panda"] 1. binary_search("elephant", animals) 2. binary_search("dog", animals) 3. binary_search("anteater", animals)arrow_forwardb. Using selection sort arrange the set of numbers: 4,7,9,1,3,6,2. How many passes will be done to make it ordered? c. Text = thequickbrownfoxjumpoverthelazydog Pattern umpo Given the text and the pattern, how many attempts will it try before it finally execute?arrow_forward
- What is the difficulty of randomized quick sort in terms of both the auxiliary space and the average amount of time it takes?arrow_forwardIn this exercise, we will be looking at our example code for Selection Sort. However, while we are sorting we will also count the number of swaps taking place, then print them out once the array has been sorted. Add a print statement at the end of the selectionSort method that prints out the number of swaps that took place during the sort. You should not modify the main() method. Hint: Where are items compared? Try writing out the steps in the algorithm on paper to help.arrow_forwardNationality. Prove the function works by testing it 2. BLACKJACK: Sample two cards from a "deck of cards" (ace, 2-10, jack, queen, king). Find the total of the two cards (ace counts as 11 and facecards count as 10). If the total is 21 print "BLACKJACK!" otherwise print "Try again". Keep drawing pairs of two cards until you get blackjack. Set your seed to 30 at the start of this problem ?
