Machine Learning: kNN Learning.

Suppose a 7-nearest-neighbors regression search returns {7, 6, 8, 4, 7, 11, 100} as the 7 nearest y (correct) values for a given x value. What is the value of (predicted value) that minimizes the L1 loss function on this data? There is a common name in statistics for this value as a function of the y values; what is it? Answer the same two questions for the L2 loss function.
