urlify | fast PHP slug generator and transliteration library

When I go to http://127.0.0.1:8000/, at the very top of the page, it says

I'm trying to write a function that urlify's a string by replacing any spaces in it, with "%20". I thought that by mapping an array and using a conditional statement to determine whether or not to return the original word would work. However, it hasn't. My map array is returning the original statement.

The images are being downloaded in RecipeApiActivity - I can see them in a test ImageView called 'imigiview', so the API Request works! But I want them to be displayed correctly in a recyclerview - now it shows nothing at all.
For that I created a list of Bitmaps in which I put all the downloaded bitmaps, this list is given to the RecipeAPIAdapter that should place them in the RecyclerView.
Can you help me find out why the images are not shown? ( The Logcat gives me no error of any kind)

I'm experimenting with Array.map() and got this little snippet, which does perform as intended:

I am trying to find all the URLs from a string for that I used the following code.

I just started using google benchmark for microbenchmarking and I got results I can't really explain. I have a function URLify(basic functions that encodes whitespaces). I convert my string to char * and pass it to the function

This is how I test it using google benchmark and Full optimization. using VS 2015 x64

I have a paragraph of strings containing links. The links have to be clickable and redirect the user to the specific pages. I have written custom pipe, but am missing the point here.

I am running django 2.0, which has jquery 2.2.3. I want to utilize this ImageViewer Javascript app https://github.com/s-yadav/ImageViewer with one of my admin pages. I added the js files and css file to the Media class within my ModelAdmin class, and collected all the static files. The files are loaded on the web page. I am following the app's example for Image Mode (http://ignitersworld.com/lab/imageViewer.html)

The page loads, but there is an error in the js console:

I took the Java code from cracking the coding interview for the urlify problem (1.3):

URLify: Write a method to replace all spaces in a string with '%20'. You may assume that the string has sufficient space at the end to hold the additional characters, and that you are given the "true" length of the string. (Note: if implementing in Java, please use a character array so that you can perform this operation in place.)

EXAMPLE

Input: "Mr John Smith , 13

Output: "Mr%2eJohn%2eSmith"

I'm having some issues with the converted code. Here is my python code:
