If we have two individually sorted vectors "a" and "b" but they are not sorted with respect to each other and we want to merge them into vector "c" such that "c" is also a sorted vector. Then c=mergesorted(a,b) can be used.
Distributed Median,Alice has an array A, and Bob has an array B. All elements in A and B are distinct. Alice and Bob are interested in finding the median element of their combined arrays.
