write a python code for these requirements, DO NOT USE ANY LOOP

Objective:

Create and train a KNN model using the input training set.

Return the trained model.

$2\mathrm{.}1\mathrm{.}2$ Requirements:

The function should be named create$\_$and$\_$train$\_$knn$\_$model $.$

Parameters:

x$\_$train : A $2$D array of the training features.

y$\_$train : A $1$D array of the training labels.

$k$ : An integer representing the number of neighbors to consider. The default value should be $1.$

Return:

The function should return the trained KNN model, which is trained onn the input training data and with the input value of $k.$
