SOLVED: Part 3: Implement knnclassifier [Graded]Implement the function knnclassifier, which should perform k nearest neighbor classification on a given test dataset. The call:preds = knnclassifier(xTr, yTr, xTe, k)should output the predictions for the data in xTe, i.e. preds[i] will contain the prediction for xTe[i,:].You may find it helpful to use f1 at ten in the implementation of this function. It will also be useful to refer back to the mode function you implemented in Additional NumPyExerci
