They have a collection of n bank cards that they’ve confiscated, suspectingthem of being used in fraud. Each bank card is a small plastic object, containing a magnetic stripe withsome encrypted data, and it corresponds to a unique account in the bank. Each account can have manybank cards corresponding to it, and we’ll say that two bank cards are equivalent if they correspond to thesame account.It’s very difficult to read the account number off a bank card directly, but the bank has a high-tech “equivalence tester” that takes two bank cards and, after performing some computations, determines whether theyare equivalent.Their question is the following: among the collection of n cards, is there a set of more than n/2 of themthat are all equivalent to one another? Assume that the only feasible operations you can do with the cardsare to pick two of them and plug them…
- An application loads 100 libraries at start-up. Loading each library requires exactly one disk access. The seek time of the disk to a random location is given as 10 ms. Rotational speed of disk is 6000 rpm. If all 100 libraries are loaded from random locations on the disk, how long does it take to load all libraries? (The time to transfer data from the disk block once the head has been positioned at the start of the block may be neglected.)Why should we use a linker? Group of answer choices A. The linker can help you find errors in your program by yelling at you when you have multiple symbols defined. B. The best practice is to actually avoid using linkers. C. We can 'link' together files that we have previously compiled, which saves us time. We can also link together files 'dynamically' which saves us overall memory on our system if those libraries are shared amongst many programs.Given the contents of the Scoreboard (capacity=5) as {[''Kristoff'', 75], ["Anna", 72], ["Elsa", 67], ["Olaf", 64]}, it would need how many movement/s or shift/s to accommodate the GameEntry ["Samantha", 75]?
- Explain the group of DEBUG commands that could be used to verify the operation of: PUSH DX as we used to do with most of the instructions we learned in class. Note that you have to mention the commands in order. Note: The typical answer should look like this: First, I will use- command to Second, I will use -- command to ---- as so on... Paragraph BIE Path: pWe analyzed a program which was supposedly used for cracking some cryptographic algorithms. During the investigations we determined that the program input size can be varied in a wide range and for N-bit input the program result is also always N bit long. Additionally we found that the program working time depends significantly on input length N, especially when N is greater than 10-15. Our test also revealed, that the program working time depends only on input length, not the input itself. During our tests, we fixed the following working times (with an accuracy of one hundredth of a second): N=2-16.38 seconds N = 5-16.38 seconds N = 10-16.44 seconds N=15-18.39 seconds N=20-1 minute 4.22 seconds We also planned to test the program for N=25 and N = 30, but for both cases the program didn't finish within half an hour and was forced to terminate it. Finally, we decided for N= 30 to not terminate the program, but to wait a little bit longer. The result was 18 hours 16 minutes 14.62…The Reflection algorithm can be used to encrypt a C-string (character array terminated with the null character) before it is transmitted over the Internet. The Reflection algorithm works as follows: Each letter in the message is converted to the letter in that is 13 positions to the right of that letter in the English alphabet. If the end of the alphabet is reached, counting continues from the first letter in the alphabet. The case of the letters must be maintained. For example,'M' →'Z', 'x' → 'k', 'A' → 'N'The numeric characters ('0' to '9') are shifted 5 positions to the right of that number in the character set '0' to '9'. If ‘9’ is reached, counting continues from ‘0’. For example,'0' → '5', '2' →'7', '8' → '3' All other characters are left as they are. a) What would the following string be encrypted to by the Reflection algorithm?“Call me at 662-2002 Ext 85393” b) Write a function, getPosition, which finds the position of a letter in the alphabet regardless of the case of the…

Write each using exactly two hex digits (using lower-case hex for a-f).You are the sysadmin for a big tech company, and you have to estimate the amount of servers you need to handle some long-running jobs. One server can handle only one job at once. One job can only be executed by one server at once. Once a server has finished executing its current job, it can be reassigned to a new job. Given an array of time intervals intervals where intervals[i] = [starti, endi], representing the start and end time for a particular job that needs to be executed, return the minimum number of servers required to run all jobs. Constraints: 1 <= intervals.length <= 104 0 <= starti < endi <= 106 Function definition for Java: public int minMeetingRooms(int[][] intervals) { // Your code here } Function definition for Python: def minMeetingRooms(self, intervals: List[List[int]]) -> int: #Your code here Announced Test Cases: Input: intervals = [[0,30],[5,10],[15,20]] Output: 2Explanation: We need one server for the job that starts at 0.
