NOTE: I am beginner in Python
I learnt the Heap sort today and tried my own implementation using Python. Can i get feedback for my code and areas of improvement. I have tried to add comments inline, but if still something is unclear, then i will add more comments.
def max_heap(listmax):
...
void selectionSortC()
{
//Not wasting time inputting arrary
int arr[6] = { 2,4,-22,4,2,1 };
size_t minIdx = 0;
int len = sizeof(arr) / sizeof(int);
for (int i = 0; i < len; i++)
{
for (int j = i + 1; j < len; j++)
{
if (arr[i] > arr[j])

I am a beginner at Java programming, and I'm always curious about how to make code more efficient or learn what I am doing wrong. I just started learning about cryptography, and this is a simple cryptography example I made.
This code adds the number 100 after each character.

I'm currently learning about Dynamic Programming and solving a "coding question" related to the topic.
Given an array of non-negative integers, you are initially positioned at the first index of the array.
Each element in the array represents your maximum jump length at that position.

I'm practicing recursive functions and I would be glad to receive some feedback for the following Python code I wrote. I did several tests and the function yielded correct results but I wonder if it can be written more concise or if it can be criticised in some way. Your feedback would help me be...
So there is an existing codebase which calculates the total time worked per month.
What the code is doing:
iterates through all the working days entries
retreives the value of net work time which is in format: HH:mm
calculates the minutes out of the net work time string
formats the net work ti...
I have two files:

So I am new to programming, and I wanted to ask, is my code inefficient / poorly written?
Here is my code below for an exercise I just did. The point is for the user to guess the number 0, but it also:
Calculates the average number
Calculates the number of attempts
Gives the sum of attempts

I am trying to accelerate my python3 script using multi-processing by running 4 processes simultaneously. However, my processes never reaches 100% CPU utilization. The core of my code simply reads a .mp3 recording and do some recognition on it using scikit-learn then saves the results to a .json....
I've been working on re-writing comfortablydrei's answer to this PPCG Question regarding creating a illusion animation in pure Excel VBA. So far, I've been able to rewrite the code to function in VBA, and to get the cycle time for the animation down substantially, but have run into an issue where...
This program is made, so it graphs a spiral with N steps.
What else could I add to this program?
Can this code be improved?

Hi I'm fairly new to coding and would appreciate some feedback on the code. This is for a site that has a dynamic login page and infinite scrolling.
I wanted to use scrapy not necessarily because it needs the framework, but because I hadn't done infinite scrolling and dynamic content with scrap...
I would like to ask if this is a bad idea.
I have a spinner that it has a custom layout with 5 imageviews and 1 textview
I would like to load it up with 80 rows, so it will display around 300 images, (all images are within the app)
Is this a really bad idea?
All the images are loaded this way:

I have implemented a custom merge of 2 pandas DataFrames, but only mutates the first.
The new columns will be the union of the original columns and the new keys will be union of original keys. Additionally, the second DataFrame values will overwrite the first DataFrame if the keys match.
