问题 This question already has answers here : How does this recursion work? (11 answers) Closed 4 days ago . So there is this recursion example in chap 3 of Eloquent JavaScript, it goes like this: Consider this puzzle: by starting from the number 1 and repeatedly either adding 5 or multiplying by 3, an infinite set of numbers can be produced. How would you write a function that, given a number, tries to find a sequence of such additions and multiplications that produces that number? And the given

问题 A newbie, I am trying to increase familiarity with OOP, building a class structure to allow for a more organized way of coding. I have several files in my structure, formulas.py , df.py and main.py , and a test.py file. Basically, I am therefore targeting elimination of test.py and df.py. Also, in class Data_Load , I have get_EDA_shape, get_EDA_describe and get_EDA_info . These are also redundant, and should be replaced by the functionality presented in def common_stats() . Now I want to

问题 I am trying to use a function I found that serves to test the significance of an object created an igraph. First the data and the libraries are loaded. Then, clustering is performed on the data. Finally, I use a function I found online in an attempt to calculate the significance of the clustering. However, this does not work. Can someone please help me understand why this function for significance testing is not working? library(igraph) library(igraphdata) data(karate) cfg <- cluster_fast

问题 I'm a university student, our teacher told us to tell the meaning of these pointers, but I only manage to figure out some of them: 1. int *p1; 2. int *p2[10]; 3. int (*p3)[10]; 4. int (*p4)(); 5. int **p5(); 6. int (**p6)[10]; 7. int (**p7)(); 8. int *(*p8)(); 9. int (*p9[10])(); 10. int **p10[10]; This is what I've figured out so far: p1 is a pointer to an int p2 is an array of 10 int pointer p3 is a pointer that point to a static-array with 10 elements p4 is a function pointer p5 is not a

问题 I am trying to find the GCD of two numbers using Euclid's algorithm in C (recursively) and I do know that mathematically it's not completely perfect yet as it neglects negative number conditions, but I just want this one to work for positive numbers for now. #include <stdio.h> int gcd(int m, int n); int main() { return gcd(60, 24); } int gcd(int m, int n) { if (m < n) { //swapping both a and b m = m + n; n = m - n; m = m - n; } if (m == n) { return m; } else { return gcd(n, m % n); } } 回答1:

问题 I currently have a code which counts the palindromes in a given string and it was working fine till I tested it with "appal" the function returned 0 when it should return 2 (appa and pp) I would really appreciate it if someone can edit my current code so that it meets that requirement, thank you! Here's my code: function countPalindromes(string, count) { if (string.length <= 1) { return count; } let [ firstLetter ] = string; let lastLetter = string[string.length - 1]; if (firstLetter ===

问题 Trying to figure out if it is possible to do a textjoin like function in SQL based on a condition. Right now the only way I can think of doing it is by running a pivot to make the rows of the column and aggregating them that way. I think this is the only way to transpose the data in SQL? Input This would be a aql table (tbl_fruit) that exists as the image depicts SELECT * FROM tbl_fruit Output 回答1: Below is for BigQuery Standard SQL (without specifically listing each column, thus in a way
