Question 1

What is the Dutch National Algorithm?

Accepted Answer

The Dutch National Algorithm is also known as a three way partitioning algorithm. It helps partitioning an array, which consists of three distinct 

values. The objective of this algorithm is to arrange these data meaningfully.

Question 2

Is the Dutch National Flag Algorithm stable?

Accepted Answer

No, the Dutch National Flag algorithm is not stable. The relative order of the elements inside the array may change.

Question 3

Who invented the 3-way partition algorithm that solves the Dutch National Flag algorithm?

Accepted Answer

The Dutch National Algorithm algorithm was proposed by the famous computer scientist Edsger Dijkstra. The Netherlands flag consists of three colors: Red, Blue, and white. The objective was to arrange them in order such that all the red color appear together and same goes for the other two colors.

Question 4

What is the Dutch National Flag Algorithm Coding Question?

Accepted Answer

The Dutch National flag algorithm objective is to arrange the three colors, namely red, blue and white, so that they all appear together. Most of the time, it is used to solve array questions consisting of three colors or integer value, such as 0s, 1s, and 2s.
