# 30 Days of Code Challenge



### About



- 30 days of code chalenge is ment to get the programmer in you running.



- Commit to a minimum of 1 hour a day of coding to sharpen your skills.



- No language restrctions.



- No topic restriction.But make make sure to keep it challenging.



- Additional description appriciated but not mandatory.



- *Descriptive comments, indentation and sensible variable names are a must.*



- Commit code + log(output) to github every 24 hours for the next 30 days.



- Don't Forget to update this Readme everyday.



## Resources

Don't know where to begin?



1) Try solving coding challenges on websites like :



	Codewars : [www.codewars.com/r/4NSWPQ](www.codewars.com/r/4NSWPQ) (Relatively Easy)



	Or tons of other challenging ones.To mention a few :



	- Hacker Earth -[https://www.hackerrank.com/](https://www.hackerrank.com/)



	- Hacker Rank - [https://www.hackerearth.com/](https://www.hackerearth.com/)



	- CodeChef - [https://www.codechef.com/](https://www.codechef.com/)



2) Try to implement basic **Datastructes** and **Algorithms** initially and   	move on to apply to other problems.



3) Move on to neich corners.Want to learn something new and specific goahead.

But make sure you putdown a meaning effort and upload anything you've written.

***Dont miss a commit just because it ain't great.***

4) Or start early and obtain the art of learning from documentation>will help you in the long run.


### Day 1

* Insertion Sort in C.(Algorithms)

	* Code file - [InsertionSort.c](https://github.com/Pythonista7/30_days_of_code-/blob/master/InsertionSort.c)

	* Log File - [InsertionSort_log.txt](https://github.com/Pythonista7/30_days_of_code-/blob/master/InsertionSort_log.txt)



* A Basic Clone of MS Paint using OpenCV in Python.(ImageProcessing)

	* Code file - [PaintBrushwCV.py](https://github.com/Pythonista7/30_days_of_code-/blob/master/PaintBrushwCV.py)

	* A sample below:

	

	![Drawing](https://github.com/Pythonista7/30_days_of_code-/blob/master/MonaLisa.png)

	



### Day 2

* Core Operations with openCV.I would highly recommend checking out the openCV documentation.They also a really good python tutorial.Click [here](https://docs.opencv.org/3.1.0/d6/d00/tutorial_py_root.html#gsc.tab=0).Topics covered today Core Operation: Basic Operations , Arithmetic and Bitwise operations.

	* Code File : [OCVCoreOps.py

](https://github.com/Pythonista7/30_days_of_code-/blob/master/OCVCoreOps.py)

	* Screen Shot :

### Day 3

* Today I was really curious to apply this to one of my [Other Project](https://github.com/Pythonista7/Sign_Language_Digit_Recognition).I've always wanted to do this.The prediciton acc might not be good but I learnt a lot of things about pipelining video data and other challenges.



	* Code File : [SignLangDigitRecogWOpenCV.ipynb](https://github.com/Pythonista7/30_days_of_code-/blob/master/SignLangDigitRecogWOpenCV.ipynb)

	* Screen Shot :

The "mask" window is rescaled to input to the CNN("img" is the input to the CNN) and the mask overlayed with the prediction of what the hand-posture is, is show displayed on the top right of the "result" window.



### Day 4

* OpenCV in python continued.Topics covered - *Geometric Transformations* and *Image Thresholding* .

  Made a detailed and explainatory jupyter notebook which covers these 2 topics and implementation.
