The time complexity of KNN algorithm is O(n log n) for training and O(kn) for testing.

• The time complexity for training the KNN algorithm is O(n log n), where n is the number of training samples.

• The time complexity for testing the KNN algorithm is O(kn), where k is the number of nearest neighbors to consider and n is the number of training samples.

• The time complexity can be further optimized using data structures like K
