question:A factory uses a robotic machine to assemble products. The robot has to perform a series of commands to complete the assembly of a product. Each command is represented by a single lowercase letter of the alphabet, where 'a' means a specific action, 'b' means another specific action, and so on up to 'z'. The robot can perform a series of commands sequentially. However, the robot's memory is limited, and it can remember only a certain number of commands at a time. If the series of commands given to the robot forms a subsequence that has a length greater than the memory limit of the robot, the robot fails to complete the assembly process. You need to write a program that checks if the robot can complete the assembly process given its memory limit. Input The first line contains an integer n (1 ≤ n ≤ 100), representing the number of commands in the series. The second line contains a string of n lowercase letters, representing the series of commands. The third line contains an integer m (1 ≤ m ≤ 100), representing the memory limit of the robot. Output Print "YES" if the robot can complete the assembly process without failing, and "NO" otherwise. Example Input 8 abcdefgh 5 Output NO Explanation: The length of the command series (8) is greater than the memory limit (5), so the robot will fail to complete the assembly process. Example Input 5 abcde 5 Output YES Explanation: The length of the command series (5) is equal to the memory limit (5), so the robot can complete the assembly process.
answer:def can_complete_assembly(n, commands, m): Returns "YES" if the robot can complete the assembly process given its memory limit, otherwise returns "NO". if n <= m: return "YES" else: return "NO"
question:You are given a grid representing a map where each cell can be either land or water. The grid cells are connected horizontally and vertically. Your task is to find all distinct islands in the grid. An island is a group of connected land cells (1s), and an island is considered distinct based on its shape, regardless of its position in the grid. The distinct islands should be identified and counted based on their shapes and configurations within the grid. Example 1: Input: [ [1, 1, 0, 0, 0], [1, 0, 0, 1, 1], [1, 1, 0, 1, 0], [0, 0, 0, 0, 0], [1, 1, 1, 0, 0] ] Output: 3 Explanation: There are 3 distinct islands in the grid. - The first island is formed by the cells (0,0), (0,1), (1,0), (2,0), (2,1). - The second island is formed by the cells (1,3), (1,4), (2,3). - The third island is formed by the cells (4,0), (4,1), (4,2). Example 2: Input: [ [1, 0, 0], [0, 1, 0], [0, 0, 1] ] Output: 1 Explanation: There is only 1 distinct island in the grid. All 1s are separate but have the same island shape configuration. Example 3: Input: [ [0, 0, 0], [0, 0, 0], [0, 0, 0] ] Output: 0 Explanation: There are no islands in the grid. Constraints: 1 <= grid.length, grid[0].length <= 300 grid[i][j] is either 0 (water) or 1 (land).
answer:def numDistinctIslands(grid): Returns the number of distinct islands in the grid. An island is represented as a group of connected land cells (1s). Distinct islands are based on their shapes and disregards their positions. if not grid or not grid[0]: return 0 rows, cols = len(grid), len(grid[0]) visited = [[False for _ in range(cols)] for _ in range(rows)] def dfs(r, c, r0, c0, path): if (r < 0 or r >= rows or c < 0 or c >= cols or grid[r][c] == 0 or visited[r][c]): return visited[r][c] = True path.append((r - r0, c - c0)) dfs(r + 1, c, r0, c0, path) dfs(r - 1, c, r0, c0, path) dfs(r, c + 1, r0, c0, path) dfs(r, c - 1, r0, c0, path) unique_islands = set() for r in range(rows): for c in range(cols): if grid[r][c] == 1 and not visited[r][c]: path = [] dfs(r, c, r, c, path) unique_islands.add(tuple(path)) return len(unique_islands)
question:A large company organizes an annual party on a Friday and wants to ensure that employees who work on-site and remotely are equally considered in the allocation of budgets and swag bags. Each employee working remotely or on-site should receive one swag bag and an equal spend from the total budget allocated for swag. If the total budget cannot be equally divided, the company would round down to the nearest dollar for each swag spend and cover the discrepancy with a reserve fund. The company needs your help to distribute the swag uniformly. Write a program to help the company determine how much each swag bag should be worth in dollars and how much will be kept in the reserve fund due to the rounding down. -----Input----- The first line of input contains a single integer T (1 leq T leq 1000), denoting the number of test cases. Each of the next T lines contains two integers N (1 leq N leq 10^6) and B (1 leq B leq 10^9) separated by a single space, where N is the number of employees and B is the total budget in dollars for that test case. -----Output----- For each test case, print a single line with two integers. The first integer is the amount of money each swag bag should be worth in dollars, and the second integer is the total amount of money kept in the reserve fund. -----Examples----- Sample Input: 3 10 100 7 75 15 200 Sample Output: 10 0 10 5 13 5
answer:def allocate_budget(T, test_cases): results = [] for i in range(T): N, B = test_cases[i] swag_value = B // N reserve_fund = B % N results.append((swag_value, reserve_fund)) return results
question:You are given a string containing letters of the alphabet and digits. Each letter should be treated as both uppercase and lowercase versions (case insensitive), and each of these characters has a corresponding digit weight (e.g., 'a' and 'A' map to 1, 'b' and 'B' map to 2, ... , 'z' and 'Z' map to 26). Digits in the string retain their own value. Your task is to calculate the total weight of the string by summing the weights of each character. -----Input:----- - The first line contains T, the number of test cases. Then follow the test cases. - Each test case contains a single string S. -----Output:----- For each test case, print the total weight of the string in a single line. -----Constraints----- - 1 leq T leq 10^3 - 1 leq |S| leq 10^5 - The string S contains only alphabets and digits. -----Sample Input:----- 2 aB2 zZ9 -----Sample Output:----- 5 61 -----EXPLANATION:----- For the first string: 'a' and 'A' have a weight of 1 'b' and 'B' have a weight of 2 '2' retains its weight of 2 Total weight = 1 + 2 + 2 = 5 For the second string: 'z' and 'Z' have a weight of 26 '9' retains its weight of 9 Total weight = 26 + 26 + 9 = 61
answer:def calculate_total_weight(T, test_cases): results = [] for case in test_cases: total_weight = 0 for ch in case: if ch.isdigit(): total_weight += int(ch) elif ch.isalpha(): total_weight += ord(ch.lower()) - ord('a') + 1 results.append(total_weight) return results
