After scanning the barcode, it is a 13-digit numerical string. To cope with scanning errors, barcodes have a “check and verify” method used to verify whether the barcode is correct. The specific calculation rules are: Extract the first 12 digits of a 13-digit string, add the odd digits to obtain S1, add the even digits to obtain S2, subtract S2 from S1, then get the remainder of division by 10, and finally take the absolute value. The resulting number should be equal to the 13th digit barcode. If they are not equal, it is an incorrect barcode. Please calculate the

Employees.txt is an employee table for a certain company, which records the ID and name of each employee: Relationships.txt records the subordinate relationships between employees. For example, the first record represents employee 7902, whose manager is employee 7566, and the 14th record represents employee 7839, who has no manager and is the top-level manager. Please return a result set that describes the hierarchical relationship of the entire table, with the following structural requirements: KingKing-BlakeKing-Blake-Allen…King-ClarkKing-Clark-Miller… Firstly, identify employee A and find their corresponding superior B through the relationship table. Then, search for B’s superior C and repeat the process. Until the

The 24 Point Game is a classic puzzle game played with playing cards. The rules of the game are as follows: Remove the Jokers from a deck of playing cards, leaving 52 cards, randomly draw 4 cards, and use the numbers on the cards (where J, Q, K, A represent 11, 12, 13, 1 respectively) in combination with addition, subtraction, multiplication, division, and parentheses to achieve a result of 24. Each card must be used once and only once. Write code to calculate 24 for any given four cards, outputting the solution in text format. A B C D 1

This article will discuss how to make a full-year calendar for a given year (e.g., 2020). Requirements: the calendar should be outputted as strings, formatted like a common calendar with each month displayed separately, and should include date and day-of-the-week information. Loop through each of the twelve months. First, calculate the month header and the weekday header, and add them to the perpetual calendar. Then, loop through all the days of a month, concatenating the dates by week, using 5 spaces to separate days. After concatenating a week, append the result to the perpetual calendar and move on to the

Please write a program to solve the following 10 questions: 1. Which question is the first question with answer ‘b’? (a) 2; (b) 3; (c) 4; (d) 5; (e) 6 2. The only two consecutive questions with identical answers are: (a) 2, 3; (b) 3, 4; (c) 4, 5; (d) 5, 6; (e) 6, 7 3. Which question has the same answer as this one? (a) 1; (b) 2; (c) 4; (d) 7; (e) 6 4. The number of questions with the answer ‘a’ is: (a) 0; (b) 1; (c) 2; (d) 3; (e) 4 5. Which question has the

In a formal document, words are separated by spaces, commas, periods, or carriage returns, and the “-” symbol indicates that the characters before and after the carriage return are connected as one word. There is currently a document MobyDick.txt that meets the above characteristics. Please find out how many different words have appeared in it, the frequency of each word, and identify the word with the highest frequency of occurrence. Read the document content and break it down into word sequences. Count the number of times each word appears, and the word with the highest number of times is the

The cycle section refers to the numerical part that loops in an infinite cyclic decimal. Infinite cyclic decimals can be represented as fractions, so given the numerator and denominator of a fraction, its cycle section can be calculated. Calculate the remainder using the numerator and denominator, and check if the remainder has appeared in the previous calculation. If the remainder has not appeared, it means that the cycle section has not appeared. Then multiply the remainder by 10 as the dividend and continue the loop calculation to find the remainder. If the remainder has occurred before, the loop ends. The

Four people play poker using a deck of playing cards. After drawing the jokers, the remaining 52 cards are shuffled and divided equally among the four people, with 13 cards per person, sorted by suit and points. Use now ♠,♥,♦,♣ to indicate the suit of playing cards, for example ♠8 represents spades 8, ♥K represents hearts K, please write a program to implement the card issuing process and output 4 sequences. Firstly, sort the 52 numbers using random numbers, divide them into 4 groups, call the subroutine, pass the current number as a parameter, calculate the corresponding card in the

The Fibonacci sequence refers to a sequence of numbers: 1, 1, 2, 3, 5, 8, 13, 21, … This sequence starts from the third term, and each term is equal to the sum of the first two terms. Output the first N terms of this sequence (N>2). Define a sequence, assign the first two terms a value of 1, then loop N-2 times, taking the last and second to last terms respectively, and append their sum to the sequence. The result is the generated Fibonacci sequence. Using recursive algorithm: A B C 1 30 [1,1] 2 for A1-2 =B1.m(-1)+B1.m(-2) >B1|=B2
