So, I was working on implementing my own version of the Statsitical Test of Homogeneity in Python where the user would submit a list of lists and the fuction would compute the corresponding chi value. One issue I found was that my function was removing decimals when performing division, resulting in a somewhat innaccurate chi… Read More How to maintain decimals when dividing with numpy arrays in Python

I’m trying to write a simple program that counts numbers that are divisible by 3 or 5 in a specific range. However, the program still fails to meet the desired execution time for some inputs. Here is the code: #include <cstdio> using namespace std; int main(){ unsigned long long int a=0, b=0, count=0; scanf("%d%d", &a,… Read More Speeding up a program that counts numbers divisable by 3 or 5

Imagine A1 is a cell that I put numbers in and A2 is a cell that will automatically give the vaule of A1 divided by 5. =A1/5 But when I enter a number to A1 with a greater than symbol (>) or a less than symbol (<) such as >15, A2 gives #VALUE! instead of… Read More Excel: Dividing a Number with Greater Than Symbol and Less Than Symbol (i.e. >15/5, <20/5, >20/5)

There was a question that I needed to find the inverse of the matrix (actually it’s about cryptography, but never mind) and to be honest the code works. Nevertheless, if you insert certain numbers into the matrix, the program just fail in to calculate it. Let me show you the code: #include <stdio.h> #include <stdlib.h>… Read More Trying to find the inverse of the matrix in C, but the program is not calculating correctly

fraction = list(input("Enter: ")) print(fraction) When Inputting "99/100" I wanted it to print ["99", "/", "100"] not [‘9’, ‘9’, ‘/’, ‘1’, ‘0’, ‘0’] >Solution : You can use ".split" for this, for example: thing1 = "abcdef" thing1.split("c") Gives the output: [‘ab’, ‘def’] If you’re bored and fancy fighting some spaghetti code for your own interest,… Read More Trying to input a fraction and split it into a list but it causes problem when the numbers are more than 1 digit
