Coding Problem: Oddly Even

Find the difference between the sum of odd and even position digits

Example:

Input 1234

Output 2

Explanation:

sum of values at odd position: 1+3=4

sum of values at even position: 2+4=6

6-4=2

Coding Problem: Sober Walk

Our hoary culture had several great persons since time immemorial and king vikramaditya’s nava ratnas(nine gems) belongs to this ilk. They are named in the following shloka: Among these, Varahamihira was an astrologer of eminence and his book Brihat Jataak is recokened as the ultimate authority in astrology. He was once talking with Amarasimha,another gem among the nava ratnas and the author of Sanskrit thesaurus, Amarakosha. Amarasimha wanted to know the final position of a person, who starts from the origin 0 0 and travels per following scheme. He first turns and travels 10 units of distance His second turn is upward for 20 units Third turn is to the left for 30 units Fourth turn is the downward for 40 units Fifth turn is to the right(again) for 50 units … And thus he travels, every time increasing the travel distance by 10 units. Code:

Image to Pencil Sketch using Python and OpenCV

In this post, we will go through a program to get a pencil sketch from an image using python and OpenCV. Step 1: To use OpenCV, import the library. Step 2: Read the Image. Step 3: Create a new image by converting the original image to grayscale. Step 4: Invert the grayscale image. We can invert images simply by subtracting from 255, as grayscale images are 8 bit images or have a maximum of 256 tones. Step 5: Blur the inverted image using GaussianBlur method in OpenCV library and invert the blurred image. Step 6: Divide the grayscale values of the image by the values of image received from step-5 ( Note: We inverted the grayscale image and we blurred this image and then again inverted it ). Diving an image from its smoothened form will highlight the edges and we get the image like Pencil Sketch. Steps Illustration: Code: Execution Output:
