This rule is triggered when there are lines that are longer than the configured line length (default: 80 characters). To fix this, split the line up into multiple lines.
This rule has an exception where there is no whitespace beyond the configured line length. This allows you to still include items such as long URLs without being forced to break them in the middle.
You also have the option to exclude this rule for code blocks and tables. To
do this, set the code_blocks
and/or tables
parameters to false.
Code blocks are included in this rule by default since it is often a requirement for document readability, and tentatively compatible with code rules. Still, some languages do not lend themselves to short lines.

The [K-means clustering]((https://en.wikipedia.org/wiki/K-means_clustering)) algorithm is a popular **unsupervised machine learning algorithm** used to group a set of data into clusters. It works by **iteratively** assigning data points to the nearest cluster centroid and then recalculating the centroids based on the new assignments. This process is repeated until the centroids no longer change significantly or a maximum number of iterations is reached.

The **time complexity** of the K-means clustering algorithm is `O(n * k * d * i)`, where `n` is the number of data points, `k` is the number of clusters, `d` is the number of dimensions in the data, and `i` is the number of iterations until convergence. The **space complexity** is `O(n * k + n * d)`, where the first term represents the space used by the centroids and classes arrays, and the second term represents the space used by the distances array.
