1. K-Nearest Neighbor. Read the data below:

Category	Length	Weight	Width
A	160	60	39
B	170	80	41
A	155	56	38
B	172	80	41
C	173	65	40
C	150	46	37
B	175	77	40

By using K-Nearest Neighbor Algorithm & the data above, please classify the class of the data below! Explain the process as well.(The sum of k must be odd.)
