As merge sort is a recursive algorithm, the time complexity can be expressed as the following recursive relation: T (n) = 2T (n/2) + O (n) 2T (n/2) corresponds to the time required to sort the sub-arrays, and O (n) is the time to merge the entire array. When solved, the time complexity will come to O (nLogn).

Yes, as you correctly assume a (true) categorical variable should be compared only for equality, not order. In general the algorithm cannot guess the nature of the feature, there has to be some parameters in the implementation which provide it with this information.
