In this post, you’ll find a collection of basic exercises for you to practice ‘Algorithms’ which is a fundamental topic in Computer Science. Each exercise includes a solution but for the absolute beginners, I recommend to try and solve the questions by yourself, without peeking at the solution. This is the best way to master algorithms over time. Enjoy!
Index equal to value
Given a sorted array T of integers, write an algorithm (using pseudocode) that searches for T[i] = i
In case of success, it will return the value of i, otherwise, it will return -1.
In this post, we’ll see how to solve a Linear Programming problem using the graphical method.
The graphical method consists of two main phases:
- Finding the solution space (the space where we have all the valid solutions) by drawing each constraint.
- Finding the optimal solution – a solution that will give us the maximum value for the objective function.
Let’s solve the following problem:
You generated a table using jQuery Datatable without loading the page, using Ajax. You wish to change the HTML of cells in a certain column after the data is processed. How to do it?
For the sake of this example, we’ll say we want to switch the data in the first column of the table into a hyperlink.
In this post we’ll see how to work with Jinja2 in your Python projects, to easily create and modify templates.
Jinja2 is widely used and you probably already noticed it if you used projects such as Flask and Ansible or even if you simply searched for a robust templating engine.I can describe its greatness for a couple of minutes if not hours, but the
I can describe its greatness for a couple of minutes if not hours, but the official doc does it much better, so I recommend to go over them to get an idea on what you can achieve by using it. This post is mainly for those who are looking for a quickstart guide.
We have the following table which is populated with data, using Ajax
Now, let’s say you want to color the table rows, based on the second column status after, the table is already filled with data:
- UNSTABLE -> Yellow
- SUCCESS -> Green
- Failure -> Red
