The ultimate guide to coding interviews. Developed by FAANG engineers, practice with real-world questions in top languages. Prep faster and get interview-ready in just a few hours.

Are you looking to land a new software engineering job? With two new languages and all-new questions, the recently updated Coderust is here to help you break into or level up in the tech industry.

Coderust was created by former hiring managers with years of experience in today’s top tech companies. The revamped course will walk you through a carefully curated set of sample problems from real-life coding interviews. Solutions are presented in six of today's leading programming languages.

Every example comes with step-by-step visualizations and solutions. Coderust empowers you to understand the underlying logic of software concepts instead of just memorizing formulas and answers. Write, compile, and execute your own code on the fly to test different approaches - all in the browser, no set up necessary!

At the end of the course, you will have deep expertise to tackle your coding interview with confidence in Ruby, Go, C++, Java, Python, or JavaScript.

Coderust: Hacking the Coding Interview

# Statement
Given an array of $n$ objects colored white, red, or blue, sort the array in place so that objects of the same color are adjacent, with the colors in the order red, white, and blue. 

This problem is known as **Dutch National Flag Problem**. The idea is to attribute a color to each number and then arrange them following the order of colors on the Dutch flag.

We'll use the integers `0`, `1`, and `2` to represent red, white, and blue, respectively.

## Constraints

Input numbers are restricted to `0`, `1`, or `2`.

# Example

Given an array of n colored objects, sort the array in place so that objects of the same color are adjacent, with the colors in a specific order.
