2 numbers are repeating and the other 4 numbers are repeating

for example, (a,a,b,b,b,b)

1. Draw out an optimal decision tree for determining the median for the problem (2,4), i.e., we assume that one number repeats with multiplicity two, and another number repeats with multiplicity 4. (There are six numbers in total.) What is the height of your decision tree? a:b c: c:d a:c a
